You save the cast operation on both operands, and you save using an if/else clause or the ternary operator. If you understand your type juggling then it's not a mystery what is happening (yes I know Mike knows his type juggling -- I'm speaking in general ;) Cheers, Rob. -- .------------------------------------------------------------. | InterJinn Application Framework - http://www.interjinn.com | :------------------------------------------------------------: | An application and templating framework for PHP.
