Exactly, I was about to write the same line to Tony. Yes, you can do everything without interfaces (and I do), but some people like the safety net of compile time checks for full implementation of the interfaces requirements... the problem is when you're testing the buildup of code for an interface, you often make function stubs until you get to them... and you might forget one ;) Cheers, Rob. -- http://www.interjinn.com Application and Templating Framework for PHP -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
