Usage of Interfaces

[Mihail]

Just a clarification from an earlier question about OO PHP. I've checked on the php.net website but still not completely sure. Should be a quick answer, I expect.When 'defining' methods in an interface, must the class that implements it use all the listed methods from the interface?Example:\[code\]interface foo { public function blah(); public function de(); public function bleh();}class bar implements foo { public function blah() { //Code here } public function bleh() { //More code here }}\[/code\]Would that work?
