title: PDO_SQLITE driver not present.. what to do?
body: <p>I see everywhere (including on the official docs) that the <strong>PDO_SQLITE</strong> driver is/should be included by default in PHP.</p>
  
  <p>However, when I look at my <code>extension_directory</code>, I see only these files:</p>
  
  <p><code>gd.so  mcrypt.so  mysqli.so  mysql.so  pdo_mysql.so  pdo.so</code></p>
  
  <p>And, as a result, a framework I'm trying to install (Symfony) tells me I need to install either the PDO_SQLITE or the SQLite3 .so extensions...</p>
  
  <p>Can anyone help? Can I just try and find the needed .so file somewhere on the web, place it in my extensions_directory and then include it in <strong>php.ini</strong>??</p>
  
  <p><strong>BTW:</strong> I'm running php 5.3.6 downloaded via apt-get on ubuntu.</p>
