Description:
------------
Sorry for me bad English - i hope you can understand me:

I created a PHP without the drivers for PDO-MySQL and tryed to use the PDO-MYSQL. Then an error-message occurs:

Uncaught exception 'PDOException' with message 'could not find driver' in $file:5 Stack trace: #0 $file(5): PDO->__construct('mysql:host=loca...', 'username', 'password') #1 {main} thrown in $file on line 5

It is not really a bug, but it is not to nice, to show the user my MySQL username and password.

Reproduce code:
---------------
$user = "username";
$pass = "password";
$dbh = new PDO('mysql:host=localhost;dbname=test', $user, $pass);

Expected result:
----------------
Error Message like:
Uncaught exception 'PDOException' with message 'could not find driver' in $file:5 Stack trace: #0 $file(5): PDO->__construct('mysql:host=loca...', 'username', 'password') #1 {main} thrown in $file on line 5
