Think of user input where you are expecting an integer and it must be a positive integer (which would ultimately be a string); it is much faster to do a quick check such as: $foo = (int) $_GET['foo']; if ($foo > 0) { .... } I'd personally not have to wrap more items around it due to a notice or warning.
