Interfaces are checked at parse time. I'm very sure you need to include the interface description before you can implement it. That makes it explicit. My example doesn't need any interface description, the interface of "wiggle()" is implicit. > the only difference is that in mine php does the check and in yours > method_exists() > does the check. I only put that there for fun. I could have skipped the check entirely. Then it would be expected that the wiggle() method existed. If the method doesn't exist then at run time the script will stop-- fortunately with a fatal error :) Cheers, Rob -- ...........................................................
