title: Error loading pdo_mysql in php built-in server
body: <p>I want to run php's built-in server (running by <code>$ php -S localhost:8888</code>) with PDO extension.
  But when I type this command into terminal it gives me:</p>
  
  <pre><code>PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20121212/pdo_mysql.so' - /usr/lib/php5/20121212/pdo_mysql.so: undefined symbol: pdo_parse_params in Unknown on line 0
  </code></pre>
  
  <p>(And when I try to use it it says that <code>PDO class not found</code>)</p>
  
  <p>The same is when I run just <code>$ php</code>. But when I start apache2 server everything looks good (the PDO extension is working). </p>
  
  <p>And the file <code>/usr/lib/php5/20121212/pdo_mysql.so</code> exists.</p>
  
  <p>Thanks for your answers!</p>
  
  <p>(running php 5 on ubuntu)</p>
