<!-- INTRODUCTION -->
<h2 id="intro">Introduction</h2>

<p> phpMyAdmin can manage a whole MySQL server (needs a super-user) as well as
    a single database. To accomplish the latter you'll need a properly set up
    MySQL user who can read/write only the desired database. It's up to you to
    look up the appropriate part in the MySQL manual.
</p>

<h3>Currently phpMyAdmin can:</h3>

<ul><li>browse and drop databases, tables, views, columns and indexes</li>
    <li>create, copy, drop, rename and alter databases, tables, columns and
        indexes</li>
    <li>maintenance server, databases and tables, with proposals on server
        configuration</li>
    <li>execute, edit and bookmark any
        <abbr title="structured query language">SQL</abbr>-statement, even
        batch-queries</li>
    <li>load text files into tables</li>
    <li>create<a href="#footnote_1"><sup>1</sup></a> and read dumps of tables
        </li>
    <li>export<a href="#footnote_1"><sup>1</sup></a> data to various formats:
        <abbr title="Comma Separated Values">CSV</abbr>,
    <abbr title="Extensible Markup Language">XML</abbr>,
    <abbr title="Portable Document Format">PDF</abbr>,
    <abbr title="International Standards Organisation">ISO</abbr>/<abbr
    title="International Electrotechnical Commission">IEC</abbr> 26300 -
    OpenDocument Text and Spreadsheet,
    <abbr title="Microsoft Word 2000">Word</abbr>,
    and L<sup>A</sup>T<sub><em class="big">E</em></sub>X formats
        </li>
    <li>import data and MySQL structures from OpenDocument spreadsheets, as well as <abbr title="Extensible Markup Language">XML</abbr>, <abbr title="Comma Separated Values">CSV</abbr>, and <abbr title="Server Query Language">SQL</abbr> files</li>
    <li>administer multiple servers</li>
    <li>manage MySQL users and privileges</li>
    <li>check referential integrity in MyISAM tables</li>
    <li>using Query-by-example (QBE), create complex queries automatically
        connecting required tables</li>
    <li>create <abbr title="Portable Document Format">PDF</abbr> graphics of
        your Database layout</li>
    <li>search globally in a database or a subset of it</li>
    <li>transform stored data into any format using a set of predefined
        functions, like displaying BLOB-data as image or download-link
        </li>
    <li>track changes on databases, tables and views</li>
    <li>support InnoDB tables and foreign keys <a href="#faq3_6">(see

    <li>synchronize two databases residing on the same as well as remote servers
        <a href="#faq9_1">(see <abbr title="Frequently Asked Questions">FAQ</abbr> 9.1)</a>
    </li>

</ul>

<h4>A word about users:</h4>
<p> Many people have difficulty
    understanding the concept of user management with regards to phpMyAdmin. When
    a user logs in to phpMyAdmin, that username and password are passed directly
    to MySQL. phpMyAdmin does no account management on its own (other than
    allowing one to manipulate the MySQL user account information); all users
    must be valid MySQL users.</p>

<p class="footnote" id="footnote_1">
    <sup>1)</sup> phpMyAdmin can compress (Zip, GZip -RFC 1952- or Bzip2 formats)
    dumps and <abbr title="comma separated values">CSV</abbr> exports if you use
    PHP with Zlib support (<code>--with-zlib</code>) and/or Bzip2 support
    (<code>--with-bz2</code>). Proper support may also need changes in
    <code>php.ini</code>.</p>

<!-- INSTALLATION -->
<h2 id="setup">Installation</h2>

<ol><li><a href="#quick_install">Quick Install</a></li>
    <li><a href="#setup_script">Setup script usage</a></li>
    <li><a href="#linked-tables">phpMyAdmin configuration storage</a></li>
    <li><a href="#upgrading">Upgrading from an older version</a></li>
    <li><a href="#authentication_modes">Using authentication modes</a></li>
</ol>

<p class="important">
    phpMyAdmin does not apply any special security methods to the MySQL database
    server. It is still the system administrator's job to grant permissions on
    the MySQL databases properly. phpMyAdmin's &quot;Privileges&quot; page can
    be used for this.
</p>

<p class="important">
    Warning for <abbr title="Apple Macintosh">Mac</abbr> users:<br />
    if you are on a <abbr title="Apple Macintosh">Mac</abbr>
    <abbr title="operating system">OS</abbr> version before
    <abbr title="operating system">OS</abbr> X, StuffIt unstuffs with
    <abbr title="Apple Macintosh">Mac</abbr> formats.<br />
    So you'll have to resave as in BBEdit to Unix style ALL phpMyAdmin scripts
    before uploading them to your server, as PHP seems not to like
    <abbr title="Apple Macintosh">Mac</abbr>-style end of lines character
    (&quot;<code>\r</code>&quot;).</p>

<h3 id="quick_install">Quick Install</h3>
<ol><li>Choose an appropriate distribution kit from the phpmyadmin.net
    Downloads page. Some kits contain only the English messages,
    others contain all languages in UTF-8 format (this should be fine
    in most situations), others contain all
    languages and all character sets. We'll assume you chose a kit whose
    name looks like <code>phpMyAdmin-x.x.x-all-languages.tar.gz</code>.
    </li>
    <li>Untar or unzip the distribution (be sure to unzip the subdirectories):
        <code>tar -xzvf phpMyAdmin_x.x.x-all-languages.tar.gz</code> in your webserver's
        document root. If you don't have direct access to your document root,
        put the files in a directory on your local machine, and, after step 4,
        transfer the directory on your web server using, for example, ftp.</li>
    <li>Ensure that all the scripts have the appropriate owner (if PHP is
        running in safe mode, having some scripts with an owner different
        from the owner of other scripts will be a
        problem). See <a href="#faq4_2">
        <abbr title="Frequently Asked Questions">FAQ</abbr> 4.2</a> and
        <a href="#faq1_26"><abbr title="Frequently Asked Questions">FAQ</abbr>
        1.26</a> for suggestions.</li>
    <li>Now you must configure your installation. There are two methods that
        can be used. Traditionally, users have hand-edited a copy of
    <code>config.inc.php</code>, but now a wizard-style setup script is
    provided for those who prefer a graphical installation. Creating a
    <code>config.inc.php</code> is still a quick way to get started and needed for some advanced features.
        <ul><li>To manually create the file, simply use your text editor to
                create the file <code>config.inc.php</code> (you can copy
                <code>config.sample.inc.php</code> to get minimal configuration
                file) in the main (top-level) phpMyAdmin directory (the one
                that contains <code>index.php</code>). phpMyAdmin first loads
                <code>libraries/config.default.php</code> and then overrides those
                values with anything found in <code>config.inc.php</code>. If the
                default value is okay for a particular setting, there is no
                need to include it in <code>config.inc.php</code>. You'll need a
                few directives to get going, a simple configuration may look
                like this:
<pre>
&lt;?php
$cfg['blowfish_secret'] = 'ba17c1ec07d65003'; // use here a value of your choice

$i=0;
$i++;
$cfg['Servers'][$i]['auth_type'] = 'cookie';
?&gt;
</pre>
                Or, if you prefer to not be prompted every time you log in:
<pre>
&lt;?php

$i=0;
$i++;
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = 'cbb74bc'; // use here your password
$cfg['Servers'][$i]['auth_type'] = 'config';
?&gt;
</pre>
                For a full explanation of possible configuration values, see the
                <a href="#config">Configuration Section</a> of this document.</li>
            <li id="setup_script">Instead of manually editing
                <code>config.inc.php</code>, you can use the
                <a href="setup/">Setup Script</a>. First you must
                manually create a folder <code>config</code> in the phpMyAdmin
                directory. This is a security measure. On a Linux/Unix system you
                can use the following commands:
<pre>
cd phpMyAdmin
mkdir config # create directory for saving
chmod o+rw config # give it world writable permissions
</pre>
                And to edit an existing configuration, copy it over first:
<pre>
cp config.inc.php config/ # copy current configuration for editing
chmod o+w config/config.inc.php # give it world writable permissions
</pre>
                On other platforms, simply create the folder and ensure that your
                web server has read and write access to it. <a href="#faq1_26">FAQ
                1.26</a> can help with this.<br /><br />

                Next, open <code><a href="setup/">setup/</a>
                </code>in your browser. Note that <strong>changes are not saved to
                disk until explicitly choose <code>Save</code></strong> from the
                <em>Configuration</em> area of the screen. Normally the script saves
                the new config.inc.php to the <code>config/</code> directory, but if
                the webserver does not have the proper permissions you may see the
                error "Cannot load or save configuration." Ensure that the <code>
                config/</code> directory exists and has the proper permissions -
                or use the <code>Download</code> link to save the config file locally
                and upload (via FTP or some similar means) to the proper location.<br /><br />

                Once the file has been saved, it must be moved out of the <code>
                config/</code> directory and the permissions must be reset, again
                as a security measure:
<pre>
mv config/config.inc.php . # move file to current directory
chmod o-rw config.inc.php # remove world read and write permissions
rm -rf config # remove not needed directory
</pre>
                Now the file is ready to be used. You can choose to review or edit
                the file with your favorite editor, if you prefer to set some
                advanced options which the setup script does not provide.</li></ul></li>
    <li>If you are using the
        <code>auth_type</code> &quot;config&quot;, it is suggested that you
        protect the phpMyAdmin installation directory because using
        config does not require a user to
        enter a password to access the phpMyAdmin installation. Use of an alternate
        authentication method is recommended, for example with
        HTTP&#8211;AUTH in a <a href="#glossary"><em>.htaccess</em></a> file or switch to using
        <code>auth_type</code> cookie or http. See the
        <a href="#faqmultiuser"> multi&#8211;user sub&#8211;section</a> of this
        <abbr title="Frequently Asked Questions">FAQ</abbr> for additional
        information, especially <a href="#faq4_4">
        <abbr title="Frequently Asked Questions">FAQ</abbr> 4.4</a>.</li>
    <li>Open the <a href="index.php">main phpMyAdmin directory</a>
        in your browser. phpMyAdmin should now display a welcome screen
        and your databases, or a login dialog if using
        <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
        authentication mode.</li>
    <li>You should deny access to the <code>./libraries</code> and
        <code>./setup/lib</code> subfolders in your webserver configuration. For
        Apache you can use supplied <a href="#glossary"><em>.htaccess</em></a> file in that folder, for other
        webservers, you should configure this yourself. Such configuration
        prevents from possible path exposure and cross side scripting
        vulnerabilities that might happen to be found in that code.</li>
    <li>
        It is generally good idea to protect public phpMyAdmin installation
        against access by robots as they usually can not do anything good
        there. You can do this using <code>robots.txt</code> file in root of
        your webserver or limit access by web server configuration, see
        <a href="#faq1_42"><abbr title="Frequently Asked Questions">FAQ</abbr> 1.42</a>.
    </li>
</ol>

<h3 id="linked-tables">phpMyAdmin configuration storage</h3>

<p> For a whole set of new features (bookmarks, comments,
    <abbr title="structured query language">SQL</abbr>-history,
    tracking mechanism,
    <abbr title="Portable Document Format">PDF</abbr>-generation, column contents
    transformation, etc.) you need to create a set of special tables. Those
    tables can be located in your own database, or in a central database for a
    multi-user installation (this database would then be accessed by the
    controluser, so no other user should have rights to it).</p>

<p> Please look at your <code>./examples/</code> directory, where you should find a
    file called <em>create_tables.sql</em>. (If you are using a Windows server, pay
    special attention to <a href="#faq1_23">
    <abbr title="Frequently Asked Questions">FAQ</abbr> 1.23</a>).</p>

<p> If you already had this infrastructure and upgraded to MySQL 4.1.2
    or newer, please use <em>./examples/upgrade_tables_mysql_4_1_2+.sql</em>
    and then create new tables by importing <em>./examples/create_tables.sql</em>.</p>

<p> You can use your phpMyAdmin to create the tables for you. Please be aware
    that you may need special (administrator) privileges to create the database
    and tables, and that the script may need some tuning, depending on the
    database name.</p>

<p> After having imported the <em>./examples/create_tables.sql</em> file, you
    should specify the table names in your <em>./config.inc.php</em> file. The
    directives used for that can be found in the <a href="#config">Configuration
    section</a>. You will also need to have a controluser with the proper rights
    to those tables (see section <a href="#authentication_modes">Using
    authentication modes</a> below).</p>

<h3 id="upgrading">Upgrading from an older version</h3>

<p> Simply copy <em>./config.inc.php</em> from your previous installation into the newly
    unpacked one. Configuration files from old versions may
    require some tweaking as some options have been changed or removed.
    For compatibility with PHP 6, remove a <code>set_magic_quotes_runtime(0);</code>
    statement that you might find near the end of your configuration file.</p>

<p> You should <strong>not</strong> copy <code>libraries/config.default.php</code>
    over <code>config.inc.php</code> because the default configuration file
    is version-specific.</p>

<p> If you have upgraded your MySQL server from a version previous to 4.1.2 to
    version 5.x or newer and if you use the phpMyAdmin configuration storage,
    you should run the <abbr title="structured query language">SQL</abbr> script
    found in <code>examples/upgrade_tables_mysql_4_1_2+.sql</code>.</p>

<h3 id="authentication_modes">Using authentication modes</h3>

<ul><li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
        authentication modes are recommended in a <strong>multi-user environment</strong>
        where you want to give users access to their own database and don't want
        them to play around with others.<br />
        Nevertheless be aware that MS Internet Explorer seems to be really buggy
        about cookies, at least till version 6.<br />
        Even in a <strong>single-user environment</strong>, you might prefer to use
        <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie mode so
        that your user/password pair are not in clear in the configuration file.
        </li>

    <li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
        authentication modes are more secure: the MySQL login information does
        not need to be set in the phpMyAdmin configuration file (except possibly
        for the <a href="#controluser">controluser</a>).<br />
        However, keep in mind that the password travels in plain text, unless
        you are using the HTTPS protocol.<br />
        In cookie mode, the password is stored, encrypted with the blowfish
        algorithm, in a temporary cookie.</li>

    <li id="pmausr">Note: this section is only applicable if
        your MySQL server is running with <code>--skip-show-database</code>.<br /><br />

        For '<abbr title="HyperText Transfer Protocol">HTTP</abbr>' and 'cookie'
        modes, phpMyAdmin needs a controluser that has <strong>only</strong> the
        <code>SELECT</code> privilege on the <em>`mysql`.`user` (all columns except
        `Password`)</em>, <em>`mysql`.`db` (all columns)</em>, <em>`mysql`.`host`
        (all columns)</em> and <em>`mysql`.`tables_priv` (all columns except
        `Grantor` and `Timestamp`)</em> tables.<br /> You must specify the details
        for the <a href="#controluser">controluser</a> in the <code>config.inc.php</code>
        file under the
        <code><a href="#cfg_Servers_controluser" class="configrule">
            $cfg['Servers'][$i]['controluser']</a></code> and
        <code><a href="#cfg_Servers_controlpass" class="configrule">
            $cfg['Servers'][$i]['controlpass']</a></code> settings.<br />
        The following example assumes you want to use <code>pma</code> as the
        controluser and <code>pmapass</code> as the controlpass, but <strong>this is
        only an example: use something else in your file!</strong> Input these
        statements from the phpMyAdmin <abbr title="structured query language">SQL
        </abbr> Query window or mysql command&#8211;line client.<br />
        Of course you have to replace <code>localhost</code> with the webserver's host
        if it's not the same as the MySQL server's one.

        <pre>
GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';
GRANT SELECT (
    Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
    Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
    File_priv, Grant_priv, References_priv, Index_priv, Alter_priv,
    Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv,
    Execute_priv, Repl_slave_priv, Repl_client_priv
    ) ON mysql.user TO 'pma'@'localhost';
GRANT SELECT ON mysql.db TO 'pma'@'localhost';
GRANT SELECT ON mysql.host TO 'pma'@'localhost';
GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
    ON mysql.tables_priv TO 'pma'@'localhost';</pre>

        If you want to use the many new relation and bookmark features:

        <pre>
GRANT SELECT, INSERT, UPDATE, DELETE ON &lt;pma_db&gt;.* TO 'pma'@'localhost';
</pre>

        (this of course requires that your <a href="#linked-tables">phpMyAdmin
        configuration storage</a> be set up).
    <br /></li>

    <li>Then each of the <em>true</em> users should be granted a set of privileges
        on a set of particular databases. Normally you shouldn't give global
        privileges to an ordinary user, unless you understand the impact of those
        privileges (for example, you are creating a superuser).<br />
        For example, to grant the user <em>real_user</em> with all privileges on
        the database <em>user_base</em>:<br />

        <pre>
GRANT ALL PRIVILEGES ON user_base.* TO 'real_user'@localhost IDENTIFIED BY 'real_password';
</pre>

        What the user may now do is controlled entirely by the MySQL user
        management system.<br />
        With <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
        authentication mode, you don't need to fill the user/password fields
        inside the <a href="#cfg_Servers" class="configrule">$cfg['Servers']</a>
        array.</li>
</ul>

<h4>'<abbr title="HyperText Transfer Protocol">HTTP</abbr>' authentication mode</h4>

<ul><li>Uses <abbr title="HyperText Transfer Protocol">HTTP</abbr> Basic authentication
        method and allows you to log in as any valid MySQL user.</li>
    <li>Is supported with most PHP configurations. For
        <abbr title="Internet Information Services">IIS</abbr>
        (<abbr title="Internet Server Application Programming Interface">ISAPI</abbr>)
        support using <abbr title="Common Gateway Interface">CGI</abbr> PHP see

        1.32</a>, for using with Apache
        <abbr title="Common Gateway Interface">CGI</abbr> see

    <li>See also <a href="#faq4_4">

        using the <a href="#glossary"><em>.htaccess</em></a> mechanism along with
        '<abbr title="HyperText Transfer Protocol">HTTP</abbr>' authentication
        mode.</li>
</ul>

<h4>'cookie' authentication mode</h4>

<ul><li>You can use this method as a replacement for the
        <abbr title="HyperText Transfer Protocol">HTTP</abbr> authentication
        (for example, if you're running
        <abbr title="Internet Information Services">IIS</abbr>).</li>
    <li>Obviously, the user must enable cookies in the browser, but this is
    now a requirement for all authentication modes.</li>
    <li>With this mode, the user can truly log out of phpMyAdmin and log in back
        with the same username.</li>
    <li>If you want to log in to arbitrary server see
        <a href="#AllowArbitraryServer" class="configrule">
        $cfg['AllowArbitraryServer']</a> directive.</li>
    <li>As mentioned in the <a href="#require">requirements</a> section, having
        the <code>mcrypt</code> extension will speed up access considerably, but is
        not required.</li>
</ul>

<h4>'signon' authentication mode</h4>

<ul><li>This mode is a convenient way of using credentials from another
    application to authenticate to phpMyAdmin.</li>
    <li>The other application has to store login information into
    session data.</li>
    <li>More details in the <a href="#cfg_Servers_auth_type">auth_type</a>
    section.</li>
</ul>
<h4>'config' authentication mode</h4>

<ul><li>This mode is the less secure one because it requires you to fill the
        <a href="#servers_user" class="configrule">
        $cfg['Servers'][$i]['user']</a> and
        <a href="#servers_user" class="configrule">
        $cfg['Servers'][$i]['password']</a> fields (and as a result, anyone who
        can read your config.inc.php can discover your username and password).
        <br />
        But you don't need to setup a &quot;controluser&quot; here: using the
        <a href="#servers_only_db" class="configrule">
        $cfg['Servers'][$i]['only_db']</a> might be enough.</li>
    <li>In the <a href="#faqmultiuser">
        <abbr title="Internet service provider">ISP</abbr>
        <abbr title="Frequently Asked Questions">FAQ</abbr></a> section, there
        is an entry explaining how to protect your configuration file.</li>
    <li>For additional security in this mode, you may wish to consider the Host
        authentication
        <a href="#servers_allowdeny_order" class="configrule">
            $cfg['Servers'][$i]['AllowDeny']['order']</a> and
        <a href="#servers_allowdeny_rules" class="configrule">
            $cfg['Servers'][$i]['AllowDeny']['rules']</a> configuration
        directives.</li>
    <li>Unlike cookie and http, does not require a user to log in when first
        loading the phpMyAdmin site. This is by design but could allow any
        user to access your installation. Use of some restriction method is
        suggested, perhaps a <a href="#glossary"><em>.htaccess</em></a> file with the
        HTTP-AUTH directive or disallowing incoming HTTP requests at
        one&#8217;s router or firewall will suffice (both of which
        are beyond the scope of this manual but easily searchable with Google).</li>
</ul>
<h4 id="swekey">Swekey authentication</h4>
<p>
The Swekey is a low cost authentication USB key that can be used in
web applications.<br /><br />
When Swekey authentication is activated, phpMyAdmin requires the
users's Swekey to be plugged before entering the login page (currently
supported for cookie authentication mode only). Swekey Authentication is
disabled by default.<br /><br />
To enable it, add the following line to <code>config.inc.php</code>:
</p>
<pre>
$cfg['Servers'][$i]['auth_swekey_config'] = '/etc/swekey.conf';
</pre>
<p>
You then have to create the <code>swekey.conf</code> file that will associate
each user with their Swekey Id. It is important to place this file outside
of your web server's document root (in the example, it is located in <code>/etc</code>). A self documented sample file is provided
in the <code>examples</code> directory. Feel free to use it with your own
users' information.<br /><br />
If you want to purchase a Swekey please visit
<a href="http://phpmyadmin.net/auth_key">http://phpmyadmin.net/auth_key</a>
since this link provides funding for phpMyAdmin.

<!-- CONFIGURATION -->
<h2 id="config">Configuration</h2>

<p> <span class="important">Warning for <abbr title="Apple Macintosh">Mac</abbr>
    users:</span> PHP does not seem to like
    <abbr title="Apple Macintosh">Mac</abbr> end of lines character
    (&quot;<code>\r</code>&quot;). So ensure you choose the option that allows to use
    the *nix end of line character (&quot;<code>\n</code>&quot;) in your text editor
    before saving a script you have modified.</p>

<p> <span class="important">Configuration note:</span>
    Almost all configurable data is placed in <code>config.inc.php</code>. If this file
    does not exist, please refer to the <a href="#setup">Quick install</a>
    section to create one. This file only needs to contain the parameters you want to
    change from their corresponding default value in
    <code>libraries/config.default.php</code>.</p>

<p> The parameters which relate to design (like colors) are placed in
    <code>themes/themename/layout.inc.php</code>. You might also want to create
    <em>config.footer.inc.php</em> and <em>config.header.inc.php</em> files to add
    your site specific code to be included on start and end of each page.</p>

<dl><dt id="cfg_PmaAbsoluteUri">$cfg['PmaAbsoluteUri'] string</dt>

        Note also that the <abbr title="Uniform Resource Locator">URL</abbr> on
        some web servers are case&#8211;sensitive.
        Don&#8217;t forget the trailing slash at the end.<br /><br />

        Starting with version 2.3.0, it is advisable to try leaving this
        blank. In most cases phpMyAdmin automatically detects the proper
        setting. Users of port forwarding will need to set PmaAbsoluteUri (<a
        href="https://sourceforge.net/tracker/index.php?func=detail&amp;aid=1340187&amp;group_id=23067&amp;atid=377409">more info</a>).
        A good test is to browse a table, edit a row and save it. There should
        be an error message if phpMyAdmin is having trouble auto&#8211;detecting
        the correct value. If you get an error that this must be set or if
        the autodetect code fails to detect your path, please post a bug

    <dt id="cfg_AllowThirdPartyFraming">$cfg['AllowThirdPartyFraming'] boolean</dt>
    <dd>Setting this to <code>true</code> allows a page located on a different

        If you are using the &quot;cookie&quot; auth_type, enter here a random
        passphrase of your choice. It will be used internally by the blowfish
        algorithm: you won&#8217;t be prompted for this passphrase. There is
        no maximum length for this secret.<br /><br />

        Since version 3.1.0 phpMyAdmin can generate this on the fly, but it
        makes a bit weaker security as this generated secret is stored in
        session and furthermore it makes impossible to recall user name from
        cookie.</dd>

    <dt id="cfg_Servers">$cfg['Servers'] array</dt>
    <dd>Since version 1.4.2, phpMyAdmin supports the administration of multiple
        MySQL servers. Therefore, a

        been added which contains the login information for the different servers.
        The first

        contains the hostname of the first server, the second
        <a href="#cfg_Servers_host" class="configrule">$cfg['Servers'][$i]['host']</a>
        the hostname of the second server, etc. In
        <code>./libraries/config.default.php</code>, there is only one section for
        server definition, however you can put as many as you need in
        <code>./config.inc.php</code>, copy that block or needed parts (you don't
        have to define all settings, just those you need to change).</dd>

    <dt id="cfg_Servers_host">$cfg['Servers'][$i]['host'] string</dt>

    <dt id="cfg_Servers_port">$cfg['Servers'][$i]['port'] string</dt>
    <dd>The port-number of your $i-th MySQL-server. Default is 3306 (leave
        blank). If you use &quot;localhost&quot; as the hostname, MySQL
        ignores this port number and connects with the socket, so if you want
        to connect to a port different from the default port, use

            <li>'cookie' authentication mode
                (<code>$auth_type&nbsp;=&nbsp;'cookie'</code>) as introduced in
                2.2.3 allows you to log in as any valid MySQL user with the
                help of cookies. Username and password are stored in
                cookies during the session and password is deleted when it
                ends. This can also allow you to log in in arbitrary server if

        <br /><br />

        As of phpMyAdmin 2.5.5 the order inside the array is used for sorting the
        databases in the left frame, so that you can individually arrange your databases.<br />
        If you want to have certain databases at the top, but don't care about the others, you do not
        need to specify all other databases. Use:
        <code>$cfg['Servers'][$i]['only_db'] = array('db3', 'db4', '*');</code>

        Since release 2.3.0 you can store comments to describe each column for
        each table. These will then be shown on the &quot;printview&quot;.
        <br /><br />

        Starting with release 2.5.0, comments are consequently used on the table
        property pages and table browse view, showing up as tool-tips above the
        column name (properties page) or embedded within the header of table in
        browse view. They can also be shown in a table dump. Please see the
        relevant configuration directives later on.<br /><br />

        Also new in release 2.5.0 is a MIME-transformation system which is also
        based on the following table structure. See <a href="#transformations">
        Transformations</a> for further information. To use the
        MIME-transformation system, your column_info table has to have the three
        new columns 'mimetype', 'transformation', 'transformation_options'.

        To allow the usage of this functionality:
        <ul><li>set up <a href="#pmadb">pmadb</a> and the phpMyAdmin configuration storage</li>

    ADD `transformation` VARCHAR( 255 ) NOT NULL,
    ADD `transformation_options` VARCHAR( 255 ) NOT NULL;

        window.<br /><br />

        Using
        <a href="#cfg_QueryHistoryMax" class="configrule">$cfg['QueryHistoryMax']</a>
        you can specify an amount of history items you want to have on hold. On
        every login, this list gets cut to the maximum amount.<br /><br />

        The query history is only available if JavaScript is enabled in your

        Since release 3.5.0 you can show recently used tables in the left navigation frame.
        It helps you to jump across table directly, without the need to select the database,
        and then select the table. Using
        <a href="#cfg_LeftRecentTable" class="configrule">$cfg['LeftRecentTable']</a>
        you can configure the maximum number of recent tables shown. When you select a table

        Since release 3.3.x a tracking mechanism is available.
        It helps you to track every <abbr title="structured query language">SQL</abbr> command which
        is executed by phpMyAdmin. The mechanism supports logging of data manipulation
        and data definition statements. After enabling it you can create versions of tables.
        <br/><br/>
        The creation of a version has two effects:

        <ul>
            <li>phpMyAdmin saves a snapshot of the table, including structure and indexes.</li>
            <li>phpMyAdmin logs all commands which change the structure and/or data of the table and links these commands with the version number.</li>
        </ul>

        Of course you can view the tracked changes. On the "Tracking" page a complete report is available for every version.
        For the report you can use filters, for example you can get a list of statements within a date range.
        When you want to filter usernames you can enter * for all names or you enter a list of names separated by ','.
        In addition you can export the (filtered) report to a file or to a temporary database.

    to avoid the display of tons of hexadecimal codes that represent BLOBs, but
    some users have real <abbr title="structured query language">SQL</abbr>
    queries that are longer than 1000 characters. Also, if a query's length
    exceeds this limit, this query is not saved in the history.</dd>

    <dt id="cfg_OBGzip">$cfg['OBGzip'] string/boolean</dt>
    <dd>Defines whether to use GZip output buffering for increased
        speed in <abbr title="HyperText Transfer Protocol">HTTP</abbr> transfers.<br />
        Set to true/false for enabling/disabling. When set to 'auto' (string),
        phpMyAdmin tries to enable output buffering and will automatically disable
        it if your browser has some problems with buffering. IE6 with a certain patch
        is known to cause data corruption when having enabled buffering.</dd>

    <dt id="cfg_PersistentConnections">$cfg['PersistentConnections'] boolean</dt>
    <dd>Whether <a href="http://php.net/manual/en/features.persistent-connections.php">persistent connections</a>
        should be used or not. Works with following extensions:
        <ul>
            <li>mysql (<a href="http://php.net/manual/en/function.mysql-pconnect.php">mysql_pconnect</a>),</li>
            <li>mysqli (requires PHP 5.3.0 or newer, <a href="http://php.net/manual/en/mysqli.persistconns.php">more information</a>).</li>

    <dt id="cfg_ExecTimeLimit">$cfg['ExecTimeLimit'] integer [number of seconds]</dt>
    <dd>Set the number of seconds a script is allowed to run. If seconds is set
        to zero, no time limit is imposed.<br />
        This setting is used while importing/exporting dump files and in the
        Synchronize feature but has no effect when PHP is running in safe mode.</dd>

    <dt id="cfg_SessionSavePath">$cfg['SessionSavePath'] string</dt>
    <dd>Path for storing session data (<a
    href="http://php.net/session_save_path">session_save_path PHP parameter</a>).</dd>

    <dt id="cfg_MemoryLimit">$cfg['MemoryLimit'] string [number of bytes]</dt>
    <dd>Set the number of bytes a script is allowed to allocate. If set
        to zero, no limit is imposed.<br />
        This setting is used while importing/exporting dump files and at some
        other places in phpMyAdmin so you definitely don't want to put here
        a too low value. It has no effect when PHP is running in safe mode.<br />
        You can also use any string as in php.ini, eg. '16M'. Ensure
        you don't omit the suffix (16 means 16 bytes!)</dd>

    <dt id="cfg_SkipLockedTables">$cfg['SkipLockedTables'] boolean</dt>
    <dd>Mark used tables and make it possible to show databases with locked
        tables (since MySQL 3.23.30).</dd>

    <dt id="cfg_ShowSQL">$cfg['ShowSQL'] boolean</dt>
    <dd>Defines whether <abbr title="structured query language">SQL</abbr> queries
        generated by phpMyAdmin should be displayed or not.</dd>

    <dt id="cfg_RetainQueryBox">$cfg['RetainQueryBox'] boolean</dt>
    <dd>Defines whether the <abbr title="structured query language">SQL</abbr>
        query box should be kept displayed after its submission.</dd>

    <dt id="cfg_CodemirrorEnable">$cfg['CodemirrorEnable'] boolean</dt>
    <dd>Defines whether to use a Javascript code editor for SQL query boxes.
        CodeMirror provides syntax highlighting and line numbers. <br />
        However, middle-clicking for pasting the clipboard contents in some Linux
        distributions (such as Ubuntu) is not supported by all browsers.</dd>

    <dt id="cfg_AllowUserDropDatabase">$cfg['AllowUserDropDatabase'] boolean</dt>
    <dd>Defines whether normal users (non-administrator) are allowed to
        delete their own database or not. If set as FALSE, the link &quot;Drop
        Database&quot; will not be shown, and even a &quot;DROP DATABASE
        mydatabase&quot; will be rejected. Quite practical for
        <abbr title="Internet service provider">ISP</abbr>'s with many
        customers.<br />
        Please note that this limitation of <abbr title="structured query language">
        SQL</abbr> queries is not as strict as when using MySQL privileges. This
        is due to nature of <abbr title="structured query language">SQL</abbr> queries
        which might be quite complicated. So this choice should be viewed as
        help to avoid accidental dropping rather than strict privilege
        limitation.</dd>

    <dt id="cfg_Confirm">$cfg['Confirm'] boolean</dt>

        </dd>

    <dt id="cfg_LoginCookieValidity">$cfg['LoginCookieValidity'] integer [number of seconds]</dt>
    <dd>Define how long is login cookie valid. Please note that php
        configuration option <a href="http://php.net/manual/en/session.configuration.php#ini.session.gc-maxlifetime">session.gc_maxlifetime</a>
        might limit session validity and if session is lost, login cookie is
        also invalidated. So it is a good idea to set <code>session.gc_maxlifetime</code>
        not lower than the value of $cfg['LoginCookieValidity'].</dd>

    <dt id="cfg_LoginCookieStore">$cfg['LoginCookieStore'] integer [number of seconds]</dt>
    <dd>Define how long login cookie should be stored in browser. Default 0
        means that it will be kept for existing session. This is recommended
        for not trusted environments.</dd>

    <dt id="cfg_LoginCookieDeleteAll">$cfg['LoginCookieDeleteAll'] boolean</dt>
    <dd>If enabled (default), logout deletes cookies for all servers,
        otherwise only for current one. Setting this to false makes it easy to
        forget to log out from other server, when you are using more of
        them.</dd>

    <dt id="cfg_UseDbSearch">$cfg['UseDbSearch'] boolean</dt>
    <dd>Define whether the "search string inside database" is enabled or not.</dd>

    <dt id="cfg_IgnoreMultiSubmitErrors">$cfg['IgnoreMultiSubmitErrors'] boolean</dt>

    <dd>If enabled, allows you to log in to arbitrary servers using cookie auth and permits to specify servers of your choice in the Synchronize dialog.
        <br /><br />

        <strong>NOTE:</strong> Please use this carefully, as this may allow users access to
        MySQL servers behind the firewall where your
        <abbr title="HyperText Transfer Protocol">HTTP</abbr> server is placed.
    </dd>

    <dt id ="cfg_Error_Handler_display">$cfg['Error_Handler']['display'] boolean</dt>
    <dd>Whether to display errors from PHP or not.</dd>

    <dt id ="cfg_Error_Handler_gather">$cfg['Error_Handler']['gather'] boolean</dt>
    <dd>Whether to gather errors from PHP or not.</dd>

    <dt id="cfg_LeftFrameLight">$cfg['LeftFrameLight'] boolean</dt>
    <dd>Defines whether to use a select-based menu and display only the current
        tables in the left frame (smaller page). Only in Non-Lightmode you can
        use the feature to display nested folders using
        <a href="#cfg_LeftFrameTableSeparator" class="configrule">$cfg['LeftFrameTableSeparator']</a>
    </dd>

    <dt id="cfg_LeftFrameDBTree">$cfg['LeftFrameDBTree'] boolean</dt>

    <dt id="cfg_LeftFrameDBSeparator">$cfg['LeftFrameDBSeparator']
    string or array</dt>
    <dd>The string used to separate the parts of the database name when showing
        them in a tree. Alternatively you can specify more strings in an array
        and all of them will be used as a separator.</dd>

    <dt id="cfg_LeftFrameTableSeparator">$cfg['LeftFrameTableSeparator'] string</dt>
    <dd>Defines a string to be used to nest table spaces. Defaults to '__'.
        This means if you have tables like 'first__second__third' this will be
        shown as a three-level hierarchy like: first &gt; second &gt; third.
        If set to FALSE or empty, the feature is disabled. NOTE: You should
        not use this separator at the beginning or end of a
        table name or multiple times after another without any other
        characters in between.</dd>

    <dt id="cfg_LeftFrameTableLevel">$cfg['LeftFrameTableLevel'] string</dt>
    <dd>Defines how many sublevels should be displayed when splitting
        up tables by the above separator.</dd>

    <dt id="cfg_LeftRecentTable">$cfg['LeftRecentTable'] integer</dt>

    <dt id="cfg_ShowTooltip">$cfg['ShowTooltip'] boolean</dt>
    <dd>Defines whether to display table comment as tool-tip in left frame or
        not.</dd>

    <dt id="cfg_ShowTooltipAliasDB">$cfg['ShowTooltipAliasDB'] boolean</dt>
    <dd>If tool-tips are enabled and a DB comment is set, this will flip the
        comment and the real name. That means that if you have a database called
        'user0001' and add the comment 'MyName' on it, you will see the name
        'MyName' used consequently in the left frame and the tool-tip shows
        the real name of the DB.</dd>

    <dt id="cfg_ShowTooltipAliasTB">$cfg['ShowTooltipAliasTB'] boolean/string</dt>
    <dd>Same as <a href="#cfg_ShowTooltipAliasDB" class="configrule">$cfg['ShowTooltipAliasDB']</a>, except this works for table names.

        When setting this to 'nested', the Alias of the Tablename is only used
        to split/nest the tables according to the
        <a href="#cfg_LeftFrameTableSeparator" class="configrule">$cfg['LeftFrameTableSeparator']</a>
        directive. So only the folder is called like the Alias, the tablename itself
        stays the real tablename.</dd>

    <dt id="cfg_LeftDisplayLogo">$cfg['LeftDisplayLogo'] boolean</dt>
    <dd>Defines whether or not to display the phpMyAdmin logo at the top of the left frame.
        Defaults to <code>TRUE</code>.</dd>

    integer</dt>
    <dd>Defines the minimum number of tables to display a JavaScript filter box above the
    list of tables in the left frame.

    <dt id="cfg_LeftDisplayServers">$cfg['LeftDisplayServers'] boolean</dt>
    <dd>Defines whether or not to display a server choice at the top of the left frame.
        Defaults to FALSE.</dd>
    <dt id="cfg_DisplayServersList">$cfg['DisplayServersList'] boolean</dt>
    <dd>Defines whether to display this server choice as links instead of in a drop-down.
        Defaults to FALSE (drop-down).</dd>
    <dt id="cfg_DisplayDatabasesList">$cfg['DisplayDatabasesList'] boolean or text</dt>
    <dd>Defines whether to display database choice in light navigation frame as links
        instead of in a drop-down. Defaults to 'auto' - on main page list is
        shown, when database is selected, only drop down is displayed.</dd>

    <dt id="cfg_LeftDefaultTabTable">$cfg['LeftDefaultTabTable'] string</dt>
    <dd>Defines the tab displayed by default when clicking the small
        icon next to each table name in the navigation panel. Possible
        values: &quot;tbl_structure.php&quot;,
        &quot;tbl_sql.php&quot;, &quot;tbl_select.php&quot;,
        &quot;tbl_change.php&quot; or &quot;sql.php&quot;.</dd>

    <dt id="cfg_HideStructureActions">$cfg['HideStructureActions'] boolean</dt>
    <dd>Defines whether the table structure actions are hidden under a
        &quot;More&quot; drop-down.</dd>

    <dt id="cfg_ShowStats">$cfg['ShowStats'] boolean</dt>
    <dd>Defines whether or not to display space usage and statistics about databases
        and tables.<br />
        Note that statistics requires at least MySQL 3.23.3 and that, at this
        date, MySQL doesn't return such information for Berkeley DB tables.</dd>

    <dt><span id="cfg_ShowServerInfo">$cfg['ShowServerInfo'] </span>boolean</dt>
    <dd>Defines whether to display detailed server information on main page.
        You can additionally hide more information by using
        <code><a href="#cfg_Servers_verbose">$cfg['Servers'][$i]['verbose']</a></code>.

        <span id="cfg_ShowCreateDb">$cfg['ShowCreateDb'] </span>boolean
    </dt>
    <dd>Defines whether to display the &quot;PHP information&quot; and
        &quot;Change password &quot; links and form for creating database or
        not at the starting main (right) frame. This setting
        does not check MySQL commands entered directly.<br /><br />

        Please note that to block the usage of phpinfo() in scripts, you
        have to put this in your <em>php.ini</em>:

        <pre>disable_functions = phpinfo()</pre>

        Also note that enabling the &quot;Change password &quot; link has no
        effect with &quot;config&quot; authentication mode: because of the
        hard coded password value in the configuration file, end users can't
        be allowed to change their passwords.</dd>

    <dt id="cfg_ShowDbStructureCreation">$cfg['ShowDbStructureCreation'] boolean</dt>
    <dd>Defines whether the database structure page (tables list) has a

    <dt id="cfg_TempDir">$cfg['TempDir'] string</dt>
    <dd>
        The name of the directory where temporary files can be stored.
        <br /><br />

        This is needed for importing ESRI Shapefiles, see
        <a href="#faq6_30"><abbr title="Frequently Asked Questions">FAQ</abbr>
        6.30</a> and to work around limitations of <code>open_basedir</code> for uploaded
        files, see <a href="#faq1_11"><abbr title="Frequently Asked Questions">FAQ</abbr>
        1.11</a>.
        <br /><br />

    If the directory where phpMyAdmin is installed is subject to an
    <code>open_basedir</code> restriction, you need to create a
        temporary directory in some directory accessible by the web
        server. However for security reasons, this directory should be outside
        the tree published by webserver. If you cannot avoid having this
        directory published by webserver, place at least an empty
        <code>index.html</code> file there, so that directory listing is not
        possible.
        <br /><br />

        This directory should have as strict permissions as possible as the only
        user required to access this directory is the one who runs the
        webserver. If you have root privileges, simply make this user owner of
        this directory and make it accessible only by it:
        <br /><br />

<pre>
chown www-data:www-data tmp
chmod 700 tmp
</pre>

        If you cannot change owner of the directory, you can achieve a similar
        setup using <abbr title="Access Control List">ACL</abbr>:

<pre>
chmod 700 tmp
setfacl -m "g:www-data:rwx" tmp
setfacl -d -m "g:www-data:rwx" tmp
</pre>

        If neither of above works for you, you can still make the directory
        <code>chmod 777</code>, but it might impose risk of other users on
        system reading and writing data in this directory.

        All those variables affect the query window feature. A <code><abbr title="structured query language">SQL</abbr></code> link
        or icon is always displayed on the left panel. If JavaScript is enabled in
        your browser, a click on this opens a distinct query window, which is
        a direct interface to enter <abbr title="structured query language">SQL</abbr> queries. Otherwise, the right panel
        changes to display a query box.<br /><br />

        The size of this query window can be customized with
        <code>$cfg['QueryWindowWidth']</code> and <code>$cfg['QueryWindowHeight']</code>
        - both integers for the size in pixels. Note that normally, those
        parameters will be modified in <code>layout.inc.php</code> for the
        theme you are using.<br /><br />

        If <code>$cfg['EditInWindow']</code> is set to true, a click on [Edit]
        from the results page (in the &quot;Showing Rows&quot; section)
        opens the query window and puts the current query
        inside it. If set to false, clicking on the link puts the <abbr title="structured query language">SQL</abbr>
        query in the right panel's query box.
        <br /><br />
        The usage of the JavaScript query window is recommended if you have a
        JavaScript enabled browser. Basic functions are used to exchange quite
        a few variables, so most 4th generation browsers should be capable to
        use that feature. It currently is only tested with Internet Explorer 6
        and Mozilla 1.x.
        <br /><br />
        If <code>$cfg['QueryHistoryDB']</code> is set to <code>TRUE</code>, all your Queries are logged
        to a table, which has to be created by you (see <a
        href="#history" class="configrule">$cfg['Servers'][$i]['history']</a>). If set to FALSE,
        all your queries will be appended to the form, but only as long as
        your window is opened they remain saved.
        <br /><br />
        When using the JavaScript based query window, it will always get
        updated when you click on a new table/db to browse and will focus if
        you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
        the query window by checking the box "Do not overwrite this query from
        outside the window" below the query textarea. Then you can browse
        tables/databases in the background without losing the contents of the
        textarea, so this is especially useful when composing a query with
        tables you first have to look in. The checkbox will get automatically
        checked whenever you change the contents of the textarea. Please
        uncheck the button whenever you definitely want the query window to
        get updated even though you have made alterations.
        <br /><br />
        If <code>$cfg['QueryHistoryDB']</code> is set to <code>TRUE</code> you can specify the amount of
        saved history items using <code>$cfg['QueryHistoryMax']</code>.
        <br /><br />
        The query window also has a custom tabbed look to group the features.
        Using the variable <code>$cfg['QueryWindowDefTab']</code> you can specify the
        default tab to be used when opening the query window. It can be set to
        either 'sql', 'files', 'history' or 'full'.</dd>

    <li><a href="#transformationsfiles">File structure</a></li>
</ol>

<h3 id="transformationsintro">1. Introduction</h3>

<p> To enable transformations, you have to setup the <code>column_info</code> table
    and the proper directives. Please see the <a href="#config">Configuration
    section</a> on how to do so.</p>

<p> You can apply different transformations to the contents of each column. The
    transformation will take the content of each column and transform it with
    certain rules defined in the selected transformation.</p>

<p> Say you have a column 'filename' which contains a filename. Normally you would
    see in phpMyAdmin only this filename. Using transformations you can transform
    that filename into a HTML link, so you can click inside of the phpMyAdmin
    structure on the column's link and will see the file displayed in a new browser
    window. Using transformation options you can also specify strings to
    append/prepend to a string or the format you want the output stored in.</p>

<p> For a general overview of all available transformations and their options,
    you can consult your
    <em>&lt;www.your-host.com&gt;/&lt;your-install-dir&gt;/transformation_overview.php</em>
    installation.</p>

<p> For a tutorial on how to effectively use transformations, see our
    <a href="http://www.phpmyadmin.net/home_page/docs.php">Link section</a> on
    the official phpMyAdmin homepage.</p>

<h3 id="transformationshowto">2. Usage</h3>

<p> Go to your <em>tbl_structure.php</em> page (i.e. reached through
    clicking on the 'Structure' link for a table). There click on
    &quot;Change&quot; (or change icon) and there you will see three new
    fields at
    the end of the line. They are called 'MIME-type', 'Browser transformation' and
    'Transformation options'.</p>

    <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
    that corresponds to the column's contents. Please note that
        transformations are inactive as long as no MIME-type is selected.</li>

    <li>The field 'Browser transformation' is a drop-down field. You can choose from a
        hopefully growing amount of pre-defined transformations. See below for information on
        how to build your own transformation.<br />

        There are global transformations and mimetype-bound transformations. Global transformations
        can be used for any mimetype. They will take the mimetype, if necessary, into regard.
        Mimetype-bound transformations usually only operate on a certain mimetype. There are
        transformations which operate on the main mimetype (like 'image'), which will most likely
        take the subtype into regard, and those who only operate on a
        specific subtype (like 'image/jpeg').<br />

        You can use transformations on mimetypes for which the function was not defined for. There
        is no security check for you selected the right transformation, so take care of what the
        output will be like.</li>

    <li>The field 'Transformation options' is a free-type textfield. You have to enter
        transform-function specific options here. Usually the transforms can operate with default
        options, but it is generally a good idea to look up the overview to see which options are
        necessary.<br />

        Much like the ENUM/SET-Fields, you have to split up several options using the format
        'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
        parsed as an array, leaving the first value the first element in the array, and so
        forth.<br />

        If you want to specify a MIME character set you can define it in the transformation_options.
        You have to put that outside of the pre-defined options of the specific mime-transform,
        as the last value of the set. Use the format "'; charset=XXX'". If you use a transform,
        for which you can specify 2 options and you want to append a character set, enter "'first
        parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
        the parameters: "'','','charset=us-ascii'".</li>
</ul>

<h3 id="transformationsfiles">3. File structure</h3>

<p> All specific transformations for mimetypes are defined through class files in
    the directory 'libraries/plugins/transformations/'. Each of them extends
    a certain transformation abstract class declared in
    libraries/plugins/transformations/abstract.</p>

<p> They are stored in files to ease up customization and easy adding of new
    transformations.</p>

<p> Because the user cannot enter own mimetypes, it is kept sure that transformations
    always work. It makes no sense to apply a transformation to a mimetype the
    transform-function doesn't know to handle.</p>

<p> There is a file called '<em>transformations.lib.php</em>' that provides some basic functions
    which can be included by any other transform function.</p>

<p> The file name convention is
    <code>[Mimetype]_[Subtype]_[Transformation Name].class.php</code>,<br />
    while the abtract class that it extends has the name
    <code>[Transformation Name]TransformationsPlugin</code>.<br /><br />
    All of the methods that have to be implemented by a transformations plug-in are: <Br />
    <ol>
        <li>getMIMEType() and getMIMESubtype() in the main class;</li>
        <li>getName(), getInfo() and applyTransformation() in the abstract class it extends.</li>
    </ol>
    </p>
    
<p>The getMIMEType(), getMIMESubtype() and getName() methods return the name of the
    MIME type, MIME Subtype and transformation accordingly. getInfo() returns the
    transformation's description and possible options it may receive and
    applyTransformation() is the method that does the actual work of the
    transformation plug-in.</p>

<p> Please see the libraries/plugins/transformations/TEMPLATE and
    libraries/plugins/transformations/TEMPLATE_ABSTRACT
    files for adding your own transformation plug-in. You can also generate a
    new transformation plug-in (with or without the abstract transformation class),
    by using
    <code>libraries/plugins/transformations/generator_plugin.sh</code> or<br />
    <code>libraries/plugins/transformations/generator_main_class.sh</code>.</p>

<p> The applyTransformation() method always gets passed three variables:</p>

<ol><li><strong>$buffer</strong> - Contains the text inside of the column. This is the text,
        you want to transform.</li>
    <li><strong>$options</strong> - Contains any user-passed options to a transform function
        as an array.</li>
    <li><strong>$meta</strong> - Contains an object with information about your column.
        The data is drawn from the output of the
        <a href="http://www.php.net/mysql_fetch_field">mysql_fetch_field()</a>
        function. This means, all object properties described on the
        <a href="http://www.php.net/mysql_fetch_field">manual page</a> are
        available in this variable and can be used to transform a column accordingly
        to unsigned/zerofill/not_null/... properties.<br />
        The $meta-&gt;mimetype variable contains the original MIME-type of the
        column (i.e. 'text/plain', 'image/jpeg' etc.)</li>
</ol>

</p>

<h4 id="faq1_6">
    <a href="#faq1_6">1.6 I can't use phpMyAdmin on PWS: nothing is displayed!</a></h4>

<p> This seems to be a PWS bug. Filippo Simoncini found a workaround (at this
    time there is no better fix): remove or comment the <code>DOCTYPE</code>
    declarations (2 lines) from the scripts <em>libraries/Header.class.php</em>
    and <em>index.php</em>.</p>

<h4 id="faq1_7">
    <a href="#faq1_7">1.7 How can I GZip or Bzip a dump or a
    <abbr title="comma separated values">CSV</abbr> export? It does not seem to
    work.</a></h4>

<p> These features are based on the <code>gzencode()</code> and <code>bzcompress()</code>
    PHP functions to be more independent of the platform (Unix/Windows, Safe Mode
    or not, and so on). So, you must have Zlib/Bzip2
    support (<code>--with-zlib</code> and <code>--with-bz2</code>).<br /></p>

<h4 id="faq1_8">
    <a href="#faq1_8">1.8 I cannot insert a text file in a table, and I get
    an error about safe mode being in effect.</a></h4>

<p> Your uploaded file is saved by PHP in the &quot;upload dir&quot;, as
    defined in <em>php.ini</em> by the variable <code>upload_tmp_dir</code> (usually
    the system default is <em>/tmp</em>).<br />
    We recommend the following setup for Apache servers running in safe mode,
    to enable uploads of files while being reasonably secure:</p>

<ul><li>create a separate directory for uploads: <code>mkdir /tmp/php</code></li>
    <li>give ownership to the Apache server's user.group:
        <code>chown apache.apache /tmp/php</code></li>
    <li>give proper permission: <code>chmod 600 /tmp/php</code></li>
    <li>put <code>upload_tmp_dir = /tmp/php</code> in <em>php.ini</em></li>
    <li>restart Apache</li>

<p> As suggested by &quot;Rob M&quot; in the phpWizard forum, add this line to
    your <em>httpd.conf</em>:</p>

    <pre>SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown</pre>

<p> It seems to clear up many problems between Internet Explorer and SSL.</p>

<h4 id="faq1_11">
    <a href="#faq1_11">1.11 I get an 'open_basedir restriction' while
    uploading a file from the query box.</a></h4>

<p> Since version 2.2.4, phpMyAdmin supports servers with open_basedir
    restrictions. However you need to create temporary directory and
    configure it as <a href="#cfg_TempDir" class="configrule">$cfg['TempDir']</a>.
    The uploaded files will be moved there, and after execution of your
    <abbr title="structured query language">SQL</abbr> commands, removed.</p>

    <a href="#faq1_15">1.15 I have problems with <em>mysql.user</em> column names.</a>

<p> In previous MySQL versions, the <code>User</code> and <code>Password</code>columns

<h4 id="faq1_16">
    <a href="#faq1_16">1.16 I cannot upload big dump files (memory,
    <abbr title="HyperText Transfer Protocol">HTTP</abbr> or timeout problems).</a>
</h4>

<p> Starting with version 2.7.0, the import engine has been re&#8211;written and these
    problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
    to take advantage of the new import features.</p>

<p> The first things to check (or ask your host provider to check) are the
    values of <code>upload_max_filesize</code>, <code>memory_limit</code> and
    <code>post_max_size</code> in the <em>php.ini</em> configuration file.
    All of these three settings limit the maximum size of data that can be
    submitted and handled by PHP. One user also said that
    <code>post_max_size</code>
    and <code>memory_limit</code> need to be larger than <code>upload_max_filesize</code>.<br /> <br />

    There exist several workarounds if your upload is too big or your
    hosting provider is unwilling to change the settings:</p>

<ul><li>Look at the <a href="#cfg_UploadDir" class="configrule">$cfg['UploadDir']</a>
        feature. This allows one to
        upload a file to the server via scp, ftp, or your favorite file transfer
        method. PhpMyAdmin is then able to import the files from the temporary
        directory. More information is available in the <a href="#config">Configuration
        section</a> of this document.</li>
    <li>Using a utility (such as <a href="http://www.ozerov.de/bigdump.php">
        BigDump</a>) to split the files before uploading. We cannot support this
        or any third party applications, but are aware of users having success
        with it.</li>
    <li>If you have shell (command line) access, use MySQL to import the files
        directly. You can do this by issuing the &quot;source&quot; command from
        within MySQL: <code>source <em>filename.sql</em></code>.</li>
</ul>

<h4 id="faq1_17">
    <a id="faqmysqlversions" href="#faq1_17">1.17 Which MySQL versions does phpMyAdmin
    support?</a></h4>

<p> Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For
    older MySQL versions, you need to use the latest 2.x branch. phpMyAdmin can
    connect to your MySQL server using PHP's classic
    <a href="http://php.net/mysql">MySQL extension</a> as well as the
    <a href="http://php.net/mysqli">improved MySQL extension (MySQLi)</a> that
    is available in PHP 5.0. The latter one should be used unless you have a
    good reason not to do so.<br />
    When compiling PHP, we strongly recommend that you manually link the MySQL
    extension of your choice to a MySQL client library of at least the same
    minor version since the one that is bundled with some PHP distributions is
    rather old and might cause problems <a href="#faq1_17a">
        (see <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17a)</a>.<br /><br />
    <a href="http://mariadb.org/">MariaDB</a> is also supported
    (versions 5.1 and 5.2 were tested).<br /><br />
    Since phpMyAdmin 3.5 <a href="http://www.drizzle.org/">Drizzle</a> is supported.
    </p>

<h5 id="faq1_17a">
    <a href="#faq1_17a">1.17a I cannot connect to the MySQL server. It always returns the error
    message, &quot;Client does not support authentication protocol requested
    by server; consider upgrading MySQL client&quot;</a></h5>

<p> You tried to access MySQL with an old MySQL client library. The version of
    your MySQL client library can be checked in your phpinfo() output.
    In general, it should have at least the same minor version as your server
    - as mentioned in <a href="#faq1_17">
    <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17</a>.<br /><br />

    This problem is generally caused by using MySQL version 4.1 or newer. MySQL
    changed the authentication hash and your PHP is trying to use the old method.
    The proper solution is to use the <a href="http://www.php.net/mysqli">mysqli extension</a>
    with the proper client library to match your MySQL installation. Your
    chosen extension is specified in <a href="#cfg_Servers_extension" class="configrule">$cfg['Servers'][$i]['extension']</a>.
    More information (and several workarounds) are located in the

<h4 id="faqmysql">
    <a href="#faqmysql">1.20 I receive the error &quot;cannot load MySQL extension, please
    check PHP Configuration&quot;.</a></h4>

<p> To connect to a MySQL server, PHP needs a set of MySQL functions called
    &quot;MySQL extension&quot;. This extension may be part of the PHP
    distribution (compiled-in), otherwise it needs to be loaded dynamically. Its
    name is probably <em>mysql.so</em> or <em>php_mysql.dll</em>. phpMyAdmin tried
    to load the extension but failed.<br /><br />

    Usually, the problem is solved by installing a software package called
    &quot;PHP-MySQL&quot; or something similar.</p>

    <a href="#faq1_22">1.22 I don't see the &quot;Location of text file&quot; field,

    <a href="#faq1_23">1.23 I'm running MySQL on a Win32 machine. Each time I create
    a new table the table and column names are changed to lowercase!</a></h4>

<p> This happens because the MySQL directive <code>lower_case_table_names</code>
    defaults to 1 (<code>ON</code>) in the Win32 version of MySQL. You can change
    this behavior by simply changing the directive to 0 (<code>OFF</code>):<br />
    Just edit your <code>my.ini</code> file that should be located in your Windows
    directory and add the following line to the group [mysqld]:</p>

<pre>set-variable = lower_case_table_names=0</pre>

<p> Next, save the file and restart the MySQL service. You can always check the
    value of this directive using the query</p>

<pre>SHOW VARIABLES LIKE 'lower_case_table_names';</pre>

<p> This can happen due to a MySQL bug when having database / table names with

    To fix this, turn off this directive, convert all database and table names
    to lower case and turn it on again. Alternatively, there's a bug-fix

    <a href="#faq1_34">1.34 Can I access directly to database or table pages?</a></h4>

<p> Yes. Out of the box, you can use <abbr title="Uniform Resource Locator">URL</abbr>s like
http://server/phpMyAdmin/index.php?server=X&amp;db=database&amp;table=table&amp;target=script. For <code>server</code> you use the server number which refers to
the order of the server paragraph in <code>config.inc.php</code>.
    Table and script parts are optional. If you want
    http://server/phpMyAdmin/database[/table][/script] <abbr title="Uniform Resource Locator">URL</abbr>s, you need to do
    some configuration. Following lines apply only for <a
    href="http://httpd.apache.org">Apache</a> web server. First make sure,
    that you have enabled some features within global configuration. You need
    <code>Options FollowSymLinks</code> and <code>AllowOverride
    FileInfo</code> enabled for directory where phpMyAdmin is installed and
    you need mod_rewrite to be enabled. Then you just need to create following
    <a href="#glossary"><em>.htaccess</em></a> file in root folder of phpMyAdmin installation
    (don't forget to change directory name inside of it):</p>

<pre>
RewriteEngine On
RewriteBase /path_to_phpMyAdmin

    <a href="#faq1_35">1.35 Can I use <abbr title="HyperText Transfer Protocol">HTTP</abbr> authentication with Apache <abbr title="Common Gateway Interface">CGI</abbr>?</a></h4>

<p> Yes. However you need to pass authentication variable to <abbr title="Common Gateway Interface">CGI</abbr> using
    following rewrite rule:</p>

<pre>
RewriteEngine On
RewriteRule .* - [E=REMOTE_USER:%{HTTP:Authorization},L]

<h4 id="faq1_37">
    <a href="#faq1_37">1.37 I run phpMyAdmin on cluster of different machines and
    password encryption in cookie auth doesn't work.</a></h4>

<p> If your cluster consist of different architectures, PHP code used for
    encryption/decryption won't work correct. This is caused by use of
    pack/unpack functions in code. Only solution is to use mcrypt extension
    which works fine in this case.</p>

<h4 id="faq1_38">
    <a href="#faq1_38">1.38 Can I use phpMyAdmin on a server on which Suhosin is enabled?</a></h4>

<p> Yes but the default configuration values of Suhosin are known to cause
    problems with some operations, for example editing a table with many
    columns and no primary key or with textual primary key.
</p>
<p>
    Suhosin configuration might lead to malfunction in some cases and it can
    not be fully avoided as phpMyAdmin is kind of application which needs to
    transfer big amounts of columns in single HTTP request, what is something
    what Suhosin tries to prevent. Generally all
    <code>suhosin.request.*</code>, <code>suhosin.post.*</code> and
    <code>suhosin.get.*</code> directives can have negative effect on
    phpMyAdmin usability. You can always find in your error logs which limit
    did cause dropping of variable, so you can diagnose the problem and adjust
    matching configuration variable.
</p>
<p>
    The default values for most Suhosin configuration options will work in most
    scenarios, however you might want to adjust at least following parameters:
</p>

<ul>
    <li><a href="http://www.hardened-php.net/suhosin/configuration.html#suhosin.request.max_vars">suhosin.request.max_vars</a> should be increased (eg. 2048)</li>

    <a href="#faq1_40">1.40 When accessing phpMyAdmin via an Apache reverse proxy, cookie login does not work.</a></h4>

<p>To be able to use cookie auth Apache must know that it has to rewrite the set-cookie headers.<br />
    Example from the Apache 2.2 documentation:</p>
<pre>
ProxyPass /mirror/foo/ http://backend.example.com/
ProxyPassReverse /mirror/foo/ http://backend.example.com/
ProxyPassReverseCookieDomain backend.example.com public.example.com
ProxyPassReverseCookiePath / /mirror/foo/
</pre>

<p>Note: if the backend url looks like http://host/~user/phpmyadmin,
    the tilde (~) must be url encoded as %7E in the ProxyPassReverse* lines.
    This is not specific to phpmyadmin, it's just the behavior of Apache.
    </p>

<pre>
ProxyPass /mirror/foo/ http://backend.example.com/~user/phpmyadmin
ProxyPassReverse /mirror/foo/

<p> Either there is an error with your PHP setup or your username/password is

    connect to local MySQL server through socket '/tmp/mysql.sock'
    (111) ...&quot; is displayed. What can I do?</a></h4>

<p> For RedHat users, Harald Legner suggests this on the mailing list:</p>

<p> On my RedHat-Box the socket of MySQL is <em>/var/lib/mysql/mysql.sock</em>.
    In your <em>php.ini</em> you will find a line</p>

<pre>mysql.default_socket = /tmp/mysql.sock</pre>

<p> change it to</p>

<pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>

<p> Then restart apache and it will work.</p>

<p> Here is a fix suggested by Brad Ummer:</p>

<ul><li>First, you need to determine what socket is being used by MySQL.<br />
        To do this, telnet to your server and go to the MySQL bin directory. In
        this directory there should be a file named <em>mysqladmin</em>. Type
        <code>./mysqladmin variables</code>, and this should give you a bunch of
        info about your MySQL server, including the socket
        (<em>/tmp/mysql.sock</em>, for example).</li>
    <li>Then, you need to tell PHP to use this socket.<br /> To do this in
        phpMyAdmin, you need to complete the socket information in the
        <em>config.inc.php</em>.<br />
        For example:
        <a href="#cfg_Servers_socket" class="configrule">
        $cfg['Servers'][$i]['socket']&nbsp;=&nbsp;'/tmp/mysql.sock';</a>
        <br /><br />

        Please also make sure that the permissions of this file allow to be readable
        by your webserver (i.e. '0755').</li>
</ul>

<p> Have also a look at the
    <a href="http://dev.mysql.com/doc/en/can-not-connect-to-server.html">

<p> When you are using a port on your localhost, which you redirect via
    port-forwarding to another host, MySQL is not resolving the localhost
    as expected.<br />
    Erik Wasser explains: The solution is: if your host is &quot;localhost&quot;
    MySQL (the command line tool <code>mysql</code> as well) always tries to use the socket
    connection for speeding up things. And that doesn't work in this configuration

<h4 id="faqthemes"><a href="#faqthemes">2.7 Using and creating themes</a></h4>

<p> Themes are configured with
    <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>,
    <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a> and
    <a href="#cfg_ThemeDefault" class="configrule">$cfg['ThemeDefault']</a>.<br />
    <br />
    Under <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>, you
    should not delete the directory &quot;pmahomme&quot; or its underlying
    structure, because this is the system theme used by phpMyAdmin.
    &quot;pmahomme&quot; contains all images and styles, for backwards
    compatibility and for all themes that would not include images or css-files.
    <br /><br />

    If <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a>
    is enabled, you can select your favorite theme on the main page. Your
    selected theme will be stored in a cookie.<br /><br /></p>

<p> To create a theme:</p>

<ul><li>make a new subdirectory (for example &quot;your_theme_name&quot;) under
        <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>
        (by default <code>themes</code>)</li>
    <li>copy the files and directories from &quot;pmahomme&quot; to
        &quot;your_theme_name&quot;</li>
    <li>edit the css-files in &quot;your_theme_name/css&quot;</li>
    <li>put your new images in &quot;your_theme_name/img&quot;</li>
    <li>edit <code>layout.inc.php</code> in &quot;your_theme_name&quot;</li>
    <li>edit <code>info.inc.php</code> in &quot;your_theme_name&quot; to
        contain your chosen theme name, that will be visible in user interface</li>
    <li>make a new screenshot of your theme and save it under
        &quot;your_theme_name/screen.png&quot;</li>
</ul>

<p> In theme directory there is file <code>info.inc.php</code> which contains
    theme verbose name, theme generation and theme version. These versions and
    generations are enumerated from 1 and do not have any direct dependence on
    phpMyAdmin version. Themes within same generation should be backwards
    compatible - theme with version 2 should work in phpMyAdmin requiring
    version 1. Themes with different generation are incompatible.</p>

<p> If you do not want to use your own symbols and buttons, remove the
    directory &quot;img&quot; in &quot;your_theme_name&quot;. phpMyAdmin will
    use the default icons and buttons (from the system-theme &quot;pmahomme&quot;).

    MySQL server</a></h4>

<p> When MySQL is running in ANSI-compatibility mode, there are some major
    differences in how <abbr title="structured query language">SQL</abbr> is
    structured (see <a href="http://dev.mysql.com/doc/mysql/en/ansi-mode.html">
    http://dev.mysql.com/doc/mysql/en/ansi-mode.html</a>). Most important of all,
    the quote-character (") is interpreted as an identifier quote character and
    not as a string quote character, which makes many internal phpMyAdmin
    operations into invalid <abbr title="structured query language">SQL</abbr>
    statements. There is no workaround to this behaviour. News to this item will
    be posted in Bug report
    <a href="https://sourceforge.net/tracker/index.php?func=detail&amp;aid=816858&amp;group_id=23067&amp;atid=377408">#816858</a>

<p> Please make sure that your table has a primary key, so that phpMyAdmin
    can use it for the Edit and Delete links.</p>

<p> phpMyAdmin uses a quick method to get the row count, and this method
    only returns an approximate count in the case of InnoDB tables. See
    <a href="#cfg_MaxExactCount" class="configrule">$cfg['MaxExactCount']</a> for
    a way to modify those results, but
    this could have a serious impact on performance.</p>

<p>
    There is no reliable way to differentiate tables in <abbr title="comma separated values">

<p>
    Currently, the import type-detection system can only assign these MySQL types to columns. In future, more will likely be added but for the time being
    you will have to edit the structure to your liking post-import.
    <br /><br />
    Also, you should note the fact that phpMyAdmin will use the size of the largest item in any given column as the column size for the appropriate type. If you
    know you will be adding larger items to that column then you should manually adjust the column sizes accordingly. This is done for the sake of efficiency.

    <a href="#faq4_1">4.1 I'm an <abbr title="Internet service provider">ISP</abbr>. Can I setup one central copy of phpMyAdmin or do I
    need to install it for each customer.
</a></h4>
<p>
    Since version 2.0.3, you can setup a central copy of phpMyAdmin for all
    your users. The development of this feature was kindly sponsored by
    NetCologne GmbH.
    This requires a properly setup MySQL user management and phpMyAdmin
    <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie authentication. See the install section on
    &quot;Using <abbr title="HyperText Transfer Protocol">HTTP</abbr> authentication&quot;.
</p>

<h4 id="faq4_2">
    <a href="#faq4_2">4.2 What's the preferred way of making phpMyAdmin secure against evil
    access.
</a></h4>
<p>
    This depends on your system.<br />
    If you're running a server which cannot be accessed by other people, it's
    sufficient to use the directory protection bundled with your webserver
    (with Apache you can use <a href="#glossary"><em>.htaccess</em></a> files, for example).<br />
    If other people have telnet access to your server, you should use
    phpMyAdmin's <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie authentication features.
    <br /><br />
    Suggestions:
</p>
<ul>
    <li>
        Your <em>config.inc.php</em> file should be <code>chmod 660</code>.
    </li>
    <li>
        All your phpMyAdmin files should be chown -R phpmy.apache, where phpmy
        is a user whose password is only known to you, and apache is the
        group under which Apache runs.
    </li>
    <li>
        Follow security recommendations for PHP and your webserver.
    </li>
</ul>

<h4 id="faq4_3">
    <a href="#faq4_3">4.3 I get errors about not being able to include a file in
    <em>/lang</em> or in <em>/libraries</em>.
</a></h4>
<p>
    Check <em>php.ini</em>, or ask your sysadmin to check it. The
    <code>include_path</code> must contain &quot;.&quot; somewhere in it, and
    <code>open_basedir</code>, if used, must contain &quot;.&quot; and
    &quot;./lang&quot; to allow normal operation of phpMyAdmin.

    <li>The username/password you specify in the login dialog are invalid.</li>
    <li>You have already setup a security mechanism for the

    <a href="#faq4_5">4.5 Is it possible to let users create their own databases?</a></h4>

<p> Starting with 2.2.5, in the user management page, you can enter a wildcard
    database name for a user (for example &quot;joe%&quot;),
    and put the privileges you want. For example,
    adding <code>SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER</code>
    would let a user create/manage his/her database(s).</p>
