title: PHP doesn't see mysql extension
body: <p>I'm at a loss.  I'm on WIndows 7 and have installed both Apache 2.2.21 and PHP 5.2.17.  I can not enable the mysql module.  Is there a known issue on Windows 7?</p>
  
  <p>I've run php --info and see the following: </p>
  
  <pre>
  C:\php>php --ini
  Configuration File (php.ini) Path: C:\WINDOWS
  Loaded Configuration File:         C:\php\php.ini
  Scan for additional .ini files in: (none)
  Additional .ini files parsed:      (none)
  </pre>
  
  <p>I've also set my extension dir inside php.ini:</p>
  
  <pre><code>extension_dir = "C:\php\ext"
  </code></pre>
  
  <p>I've also added an entry to my httpd.conf file:</p>
  
  <pre><code># configure the path to php.ini
  PHPIniDir "c:/php"
  </code></pre>
  
  <p>And yes, inside my php.ini file I've enabled the php_mysql extension and restarted my web server.</p>
  
  <p>What am I missing?</p>
