Tera-WURFL is a PHP & MySQL based library that uses the Wireless Universal Resource File (WURFL) to identify specific mobile device capabilities and features.
branch: master


ScientiaMobile WURFL API, Database Edition (formerly Tera-WURFL)


The Database-Edition WURFL API is a PHP library with database backend support
for MySQL, Microsoft SQL Server and MongoDB that uses the Wireless Universal 
Resource File (WURFL) to detect the capabilities of mobile devices.  This API
is copyrighted by ScientiaMobile, and was originally written by Steve Kamerman,
COO of ScientiaMobile, Inc.

1. Copy the files into a directory on your webserver that can be accessed
   from the Internet.  For the purposes of explaination I will refer to this
   location as, with a local directory
   of /var/www/Tera-Wurfl/.
2. Open a web browser and go to:
   you should see the "Tera-WURFL Installation" page with a bunch of errors
   on it.  The next steps will show you how to correct these errors.  You 
   can refresh this page to verify that your changes have taken effect.

3. Copy TeraWurflConfig.php.example to TeraWurflConfig.php, then edit it.
   Each setting is described in comments.  The only thing you NEED to modify
   is the database info (user, pass, db, etc).

4. By default, the DATADIR is set to "data/".  This directory holds the
   wurfl.xml file, your patch file(s) and the log file.  This directory
   and EVERYTHING in it needs to be accessible (read+write) by the user
   that runs your webserver. This is normally "apache", "www-data" or 
   "nobody" in Linux. (chown -R apache:apache ./data/)
5. Verify that the permissions errors on the installation page are fixed
   by refreshing the browser.
6. Create a new database for Tera-WURFL and a user that has a minimum of
   the following privileges on the new database:
7. In the config file, set the DB_HOST, DB_USER, DB_PASS and DB_SCHEMA.
8. Verify that the database errors on the installation page are fixed
   by refreshing the browser.  If the database tables don't exist yet
   they will be created for you when you load the WURFL file.

9. If you are satisfied with the results on the installation page, you
   can load the database with the WURFL data.  There are three sources
   that the data can come from:
   a. Your local WURFL file
      This will load the DATADIR/wurfl.xml file into your database.
   b. The current released WURFL
      This will download the current wurfl.xml file from the official
      WURFL website and load it into your database.
   c. The current CVS WURFL
      This will download the current unreleased CVS wurfl.xml file from
      the official WURFL website and load it into your database.
10.There will be a delay while the server loads/downloads the WURFL, then
   you should see something like this:

Update Complete!
   If there are errors, they are most likely problems connecting to the WURFL
   site or permission problems trying to write the temporary downloaded file
   to the DATADIR directory.  Also, many users have reported a "memory allocation"
   error - to fix this look for "OVERRIDE_MEMORY_LIMIT" in the config file. If 
   there are no errors, click on "Return to administration tool".

11.Verify that the WURFL is loaded by clicking on "Statistics, Settings,
   Log File".  You should see that there is data in your MERGE and INDEX
   tables. The CACHE table will fill up with cached data as devices access
   your site, and it will be cleared ONLY if you click on "Clear the device
   cache" from main administration page.
12.Click on "Tera-WURFL test script" to test the installation.  You can
   type in any user agent to search for it in the WURFL.  If you have caching
   enabled (default), the first time you search for a user agent you will see
   the total number of queries that Tera-WURFL performed to find a match
   (unless there was no match).  If there was a match, the device will be
   cached and the next time you search for it you will see "Total Queries: 1
   (Found in cache)".  Tera-WURFL only needed to perform 1 query since the
   devices full capabilities were cached.  If you go back to the admin page
   and look at the settings, you will see that the CACHE now has
   a couple rows in it.  You can verify the device was cached properly by going
   to "Cache Browser" from the main page and clicking on your user agent.
13.You should delete the admin/install.php file if everything is working ok.
14.Protect your 'admin' directory by using a method specific to your web
   server software.  For Apache, this means a .htaccess file would work:

Here is a very simple example:
// Include the Tera-WURFL file

// instantiate the Tera-WURFL object
$wurflObj = new TeraWurfl();

// Get the capabilities of the current client.

// see if this client is on a wireless device (or if they can't be identified)
	echo "<h2>You should not be here</h2>";

// see what this device's preferred markup language is
echo "Markup: ".$wurflObj->getDeviceCapability("preferred_markup");

// see the display resolution
$width = $wurflObj->getDeviceCapability("resolution_width");
$height = $wurflObj->getDeviceCapability("resolution_height");
echo "<br/>Resolution: $width x $height<br/>";

The complete list of capabilities is available here:
If you use $wurflObj->getDeviceCapability("cap_name") you can just use the capability name from
the WURFL site, otherwise you can access it directly from the wurfl object's
capabilities array like this: $wurflObj->capabilities['group_name']['cap_name']

Please see the test script (check_wurfl.php) for another example of usage.
