PHP ldap_connect() problems

Question

I am trying to get ldap_connect to work properly. It will work fine via CLI, but not when I open my php file via browser.

Here is what I believe are the relevant details:

• Error message: Fatal error: Call to undefined function ldap_connect() in F:\\Websites\\ldap.php on line 4
• OS: Windows Server 2008 R2 x64
• PHP Directory: C:\\Program Files (x86)\\PHP
• libeay32.dll and ssleay32.dll have been added to both C:\\Program Files (x86)\\Apache Software Foundation\\Apache2.2\\bin and C:\\Windows\\System32. They were copied from C:\\Program Files (x86)\\PHP.

Lines added to httpd.conf:

• LoadModule php5_module "C:/Program Files (x86)/PHP/php5apache2_2.dll"
• AddType application/x-httpd-php .php
• PHPIniDir "C:/Program Files (x86)/PHP"

Things changed in php.ini:

• extension_dir = "C:/Program Files (x86)/PHP/ext" (path set)
• extension=php_ldap.dll (uncommented this line)

I'm pulling my hair out, so I am more than happy to try anything people suggest.

Answer 1

Your PHP installation uses two different ini files - one when running from the command line, and a different one when running through Apache. This is evidenced by the fact that it works from the CLI, but not in a browser.

You can find the paths to the two files using phpinfo() (in a browser) and by passing the -i flag to php from the command line. Near the top of both sets of output you will find the path to the ini file in use, and I would be mighty surprised if they were identical. From the command line you can get more detailed information by passing the --ini flag.

The fact that you are getting Call to undefined function ldap_connect() can only mean that the LDAP extension was not loaded, and this can only be true through Apache but not through the CLI if they use two different ini files.

I feel silly now. The problem was with adding my PHP directory to the PATH environment variable. I'm not 100% sure why it fixed the problem, but that was what ended up doing it. Thanks for the help, guys!
