title: PDO error on the updated PHP 5.3.6 from 5.2.x
body: <p>Actualy my server updated PHP to 5.3.6 from 5.2.x. After this- all my mysql connections failed. I catch such PDO error
               <strong>Connection failed: SQLSTATE[HY000] [2002] No such file or directory</strong>
  Also checked in php.ini file value of the <strong>pdo_mysql.default_socket</strong> which is <strong>/tmp/mysql.sock</strong></p>
  
  <p>Host service told me to repair my mysql DB passwords. But it didn't help.
  Can somebody help me with this issue?</p>
