In Response to Zigbigidorlu:
Using if (!$_POST['foo']) is not the best way to test if a variable is empty/set. Doing
that creates a E_WARNING error for an uninitialized variable, and if you are planning to use a
rather high error level, this is not the better way, since this will create an error whereas if
(!isset($_POST['foo'])) or (empty($_POST['foo'])) doesn't echo an error,
just returns true/false appropriately.
One example of this is in the phpBB code - the coding guidelines state that you have to use isset()
or empty() to see if a variable is set, since they planned to use a higher level of error reporting.
