RE: [PHP] Weird pdo-mysql behavior

Perhaps when you try to make the connection you should check the return value and use whatever PDO error-checking methods exist to find out what went wrong, instead of blindly going forward assuming you have a database connection when you don't. Ditto for any result of ->query() What you are doing now is akin to turning the key in a car, not listening to see if it started, and asking a mechanic on the phone why the gas pedal doesn't work... :-)
