PDO not throwing any exceptions
If you want pdo to thow exception so that you can see what is going on kinda thing.. you can add the following parameter when you instantiate PDO just next to the password part of the pdo
array(PDO::ATTR_EMULATE_PREPARES => false, PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION)
**Note: This is not the best way to handle exception by any means!!
