Can you tell me what the function of PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION ?I've read the php manual, but i still dont understand that...If i remove the setattributte method, it looks alright too... What's the function of that actually ?

It is the one of the 3 error mode in PDO. if error mode is set to ERRMODE_EXCEPTION it will throw exception when an error occurs in database. There is more two mode-silent,warning. warning will show error as PHP warning without halting the script. Where as silent will do nothing, you need to use errorInfo() or errorCode() to see the errors. using exception is better option among the others.
