title: Why am I getting the error "Class PDO not found" in this situation?
body: <p>I am getting the following error even though I have PDO installed and included in my php.ini.</p>
  
  <p>What could I be possibly missing? I am using doctrine and codeigniter</p>
  
  <pre><code>&lt;div style="border:1px solid #990000;padding-left:20px;margin:0 0 10px 0;"&gt;
  
  &lt;h4&gt;A PHP Error was encountered&lt;/h4&gt;
  
  &lt;p&gt;Severity: Warning&lt;/p&gt;
  &lt;p&gt;Message:  Doctrine\ORM\Query\ParameterTypeInferer::inferType() [&lt;a href='doctrine\orm\query\parametertypeinferer.infertype'&gt;doctrine\orm\query\parametertypeinferer.infertype&lt;/a&gt;]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/Chicago' for 'CDT/-5.0/DST' instead&lt;/p&gt;
  &lt;p&gt;Filename: Query/ParameterTypeInferer.php&lt;/p&gt;
  &lt;p&gt;Line Number: 70&lt;/p&gt;
  
  &lt;/div&gt;&lt;br /&gt;
  &lt;b&gt;Fatal error&lt;/b&gt;:  Class 'PDO' not found in &lt;b&gt;/home/mrwongs/public_html/engine/application/third_party/Doctrine/ORM/Query/ParameterTypeInferer.php&lt;/b&gt; on line &lt;b&gt;70&lt;/b&gt;&lt;br /&gt;

  <p>My phpinfo can be seen at: <a href="http://173.203.85.196/test.php" rel="nofollow">http://173.203.85.196/test.php</a></p>
  
  <p>In my php.ini I have the following 2 lines:</p>
  
  <pre><code>extension=pdo.so
  extension=pdo_mysql.so
  </code></pre>
