That does not work for foreign/internal interfaces/base classes. Again: Why should we add this strictness? Since PHP is loosely typed, you can't guarantee that a class is implementing an interface correctly even if the method accepts the same number of arguments... I am NOT saying that Interfaces are useless (or would be without strict arguments checking). What about this case: interface A { public function doSomething($integer1, $integer2); } interface B { public function doSomething(MyObject $obj); } class Impl implements A, B { // "Overloaded" - supports both doSomething() interfaces public function doSomething() { // Use var_args to distinquish the two doSomething()'s } } -- Ferdinand Beyer <fb@fbeyer.com>
