title: Not Loading Firebird Extension
body: <p>I'm trying to use the Firebird extension in PHP. I've got the extension files (<code>php_pdo_firebird.dll, php_interbase.dll</code>) in my <code>ext</code> folder. I'm adding them in my <code>php.ini</code> file like so</p>
  
  <pre><code>...
  [PHP_PDO_FIREBIRD]
  extension=php_pdo_firebird.dll
  [PHP_INTERBASE]
  extension=php_interbase.dll
  ...
  </code></pre>
  
  <p>No errors are being thrown saying the extensions could not be loaded and yet whenever I print my <code>phpinfo</code> I don't see either of them listed. What am I missing here?</p>
  
  <p>For what it's worth, I'm running PHP version 5.3.14 TS using Apache 2.2 on Windows 7.</p>
  
  <p><strong>Edit:</strong> It seems some errors are being logged, it's just that my <code>error_log</code> setting was being overwritten (for those seeing this, double check C:\Windows\Temp\php-errors.log). Now it's telling me the specified modules could not be found whenever the file clearly exists.</p>
