extension shows in phpinfo() but not in php -m

[sam452]

My phpbrew is 1.18.5, using php 5.4.34 as default and I'm encountering some behavior that I believe I've narrowed down to phpbrew. My SO post is here: http://serverfault.com/questions/692072/call-to-undefined-function-ldap-connect-in-ubuntu?noredirect=1#comment853351_692072

tl:dr; ldap extension is reported to be enabled for apache2 as evidenced by phpinfo() and in apache's mods-enabled.

However, when I run php -m in the command line it reports these: Core, ctype, curl, date, dom, ereg, filter, gd, gettext, hash, json, libxml, mbstring, mcrypt, mhash, mysql, mysqli, mysqlnd, openssl, pcre, PDO, pdo_mysql, Phar, readline, Reflection, session, SimpleXML, soap, SPL, standard, tokenizer, xml, xmlreader, xmlwriter, xsl, zip, zlib
ldap is not one of them.

I attempted to manually enable the extension using phpbrew config, but when restarting apache it returns that it cannot because the ldap module is already enabled.

phpldapadmin still reports that the extension is not enabled and php -m confirms it's not. What am I not understanding about this apparent disconnect? thx, sam

Is your php apache module compiled with phpbrew +apxs? it looks like your command-line php is different from your php apache module.

[c9s]

Please check your apache config of loading php apache module, e.g. LoadModule php5_module modules/libphp5.4.17.so

If you used phpbrew with +apxs variant, you shall see the version name suffix.

[sam452]

Thank you very much for responding. I believe I set up this php with apxs but how to prove it? My apache config? Apache2.conf reports no modules and that's not right. Perhaps you mean my /etc/apache2/mods-enabled? I can see php5.conf, php5.load. I have been using a2enmod to enable modules. The output of phpbrew info can be found here: https://gist.github.com/sam452/7eaba7cdd129d020d8e7

But that's the phpbrew side, you seem to be asking about apache's config. I'm unsure of which config you're referring to?

[c9s]

@sam452 your phpbrew setup looks correct, but you have to confirm that your apache loads the correct module. try phpinfo() from your apache, and you can see the build information.

[c9s]

Can you also try to grep under /etc/apache2 ?

grep -r 'LoadModule php5_module' /etc/apache2

And

ls -l /usr/lib/apache2/modules

[sam452]

Happy to provide this info: The grep returns:
/etc/apache2/httpd.conf:#LoadModule php5_module libexec/apache2/libphp5.so
/etc/apache2/httpd.conf:LoadModule php5_module /usr/local/opt/php54/libexec/apache2/libphp5.so
/etc/apache2/original/httpd.conf:#LoadModule php5_module libexec/apache2/libphp5.so

And I have no directory called /usr/lib/apache2/modules. This is new to me as I thought as part of apache's new module system they are enabled from the cli?

my phpinfo output is here: https://gist.github.com/sam452/496b81dfec6eee876d5e

Looks like your apache2 is running the php you installed via homebrew, not the one you installed from phpbrew. please see the line below:

[c9s]

Can you also post your build log file? e.g. /home/sam/.phpbrew/build/php-5.4.34/build.log

[sam452]

Yes, happily: https://gist.github.com/dea3c9b70a4ac7d344b2. I was unaware I should have installed apache using phpbrew? Should I change the pointers you found? Unsure where you found it. Wait, my apache that I'm using on my Ubuntu VM was installed by apt-get, I believe. But there does seem to be a cross contamination. How to approach resolving this?

[c9s]

no, you can't change it, it's just the settings you used for building php.

I found the apxs2 detection failed in your build log:

AH00526: Syntax error on line 74 of /etc/apache2/apache2.conf:
Invalid Mutex directory in argument file:${APACHE_LOCK_DIR}

Seems like you have a syntax error in /etc/apache2/apache2.conf so apxs2 failed to read your config file.

[c9s]

The actual steps are:

• Install apache2 via system's package manager, e.g. apt-get or yum.
• run which apxs2 to make sure you have apxs2.
• use phpbrew with +apxs2=$(which apxs2) to specify the apxs binary
• then phpbrew should compile one libphp***.so file for your apache2.

[c9s]

Please also take a look at https://github.com/phpbrew/phpbrew/wiki/Cookbook#apache2-support

[sam452]

Yes, I remember running which apxs2 in this php variant. => /usr/bin/apxs2. Perhaps I should reinstall php 5.4.34 with all the variants and see if the build error occurs again. Unless I should overwrite my ubuntu apache build and all its vhosts? Also I have no /opt/local/ on this Ubuntu install.

[c9s]

Can you show me the line 74 of /etc/apache2/apache2.conf? or if you don't mind, could you send me your /etc/apache2/apache2.conf I can check detail for you.

my mail: yoanlin93@{gmail}

[c9s]

No you don't have to overwrite the whole apache, you just need the php5 module file.

[c9s]

Hi Sam!

I've found the cause, please take a look at:
http://serverfault.com/questions/558283/apache2-config-variable-is-not-defined

It seems that you need to source the apache envvars files to load the environment variables before running the build command:

source /etc/apache2/envvars

You can validate the config by running:

/usr/sbin/apache2 -V

Cheers,
c9s

[sam452]

Yes, the envvars are sourced and the apxs2 appears to be found using the Apache 2.0 handler-module support via DSO.
But my original problem still exists: Apache sees the ldap is enabled, but the CLI does not. I've tried reinstalling the ldap extension by using
phpbrew ext install ldap
The build log shows this nugget at the end:

checking for LDAP support... yes, shared
checking for LDAP Cyrus SASL support... no
configure: error: Cannot find ldap libraries in /usr/lib.

OK, running whereis ldap yields the following:
ldap: /etc/ldap /usr/lib/ldap /usr/include/ldap.h /usr/share/man/man3/ldap.3.gz

Why do you suppose phpbrew is not finding this library unless the /usr/lib/ldap directory is empty? (It's not). Thx for reading this far, sam

[c9s]

If you know where the header files of LDAP is, you can specify double dash to pass the configure options:

phpbrew ext install ldap  --  --with-ldap=.... 

please note I am not familiar with LDAP so the option name might be wrong. you can use show command to show the configure options:

phpbrew ext show ldap

[sam452]

Yes, for me in Ubuntu the correct command was found here: https://gist.github.com/kherge-old2/a7172c7102fbd738837d
phpbrew ext install ldap -- --with-libdir=lib/x86_64-linux-gnu
