Exception Handling for MySQL DB

[detestableguy]

I wrote the following for handling DB errors...the problem is, with incorrect DB connection details, other than getting "Error: Could not connect!", I am also getting mysql_connect() error

 

"Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'root'@'localhost' (using password: YES) in D:\xampplite\htdocs\web\testpages\oop\test.php on line 6

Error: Could not connect! "

 

Can you anybody please tell me why am I getting mysql_connect() error?...to best of my knowledge, I should be getting only first one if I use incorrect infornation

 

<?php

 

class ServerException extends Exception{}

 

  try {

if(!mysql_connect("localhost","root",""))

{       

            throw new ServerException("Could not connect!");

        }

 

  }

  catch (ServerException $e) {

      echo "Error: ".$e->getMessage();

  }

 

 

?>
