Example
In this example, we will try to log into a MySQL server using the wrong username and password:
<?php
$con = mysql_connect("localhost","wrong_user","wrong_pwd");
if (!$con)
{
die();mysql_error(););
}
mysql_close($con);
?>
Output similar to:
Access denied for user 'wrong_user'@'localhost' (using password: YES)
