title: PHP PDO exception: could not find driver
body: <p>Does the MySQL-server and PHP5-MySQLi version have to match in order for a connection to be possible?  I'm currently receiving the error below:  I am running BSD.
  "Fatal error: Uncaught exception 'PDOException' with message 'could not find driver'..."</p>
  
  <p>Here is the the connection info:</p>
  
  <pre><code>$info = "mysql:dbname=myDB;host=localhost";
  $user = "dbUser";
  $pw = "somePW";
  return(new PDO($info, $user, $pw));
  </code></pre>
  
  <p>Here is my MySQL information:</p>
  
  <p>mysql-server-5.5.24</p>
  
  <p>php5-mysqli-5.4.3</p>
