ID: 53081 Comment by: giorgio dot liscio at email dot it Reported by: giorgio dot liscio at email dot it Summary: why you should bring back abstract static methods Status: Bogus Type: Feature/Change Request Package: Class/Object related PHP Version: 5.3.3 Block user comment: N New Comment: but it is not allowed :( Previous Comments: ------------------------------------------------------------------------ [2010-10-16 08:43:14] ras...@php.net Right, that is exactly how it should work. ------------------------------------------------------------------------ [2010-10-16 08:36:35] giorgio dot liscio at email dot it i know, but: abstract class cA { //static function A(){self::B();} error, undefined method static function A(){static::B();} // good abstract static function B(); } class cB extends cA { static function B(){echo "ok";} } cB::A(); ------------------------------------------------------------------------ [2010-10-16 08:27:01] ras...@php.net No, you are calling a method in an abstract class. The fundamental characteristic of an abstract class is that you cannot call methods in them. ------------------------------------------------------------------------ [2010-10-16 08:15:46] giorgio dot liscio at email dot it hi Rasmus, what an honor! can you please give me some example code? you are saying that self:: points to an abstract not-implemented method? for example: abstract class cA { static function A(){self::B();} abstract static function B(); } in this case can be thrown an error, but using static:: the call refers to the called class method, not the declaring class static function A(){static::B();} so it can be re-enabled in this case, no? in php static methods are really powerful unlike java's, c#'s, don't limit them! why interfaces allows static abstract methods? how self:: is resolved? ------------------------------------------------------------------------ [2010-10-16 07:21:47] ras...@php.net Sorry, I re-read that explanation, that didn't make sense. I meant to say that methods in an abstract class require that any instance of that class implement those methods, but static methods belong to the class, not an instance. You can't call methods from an abstract class, you can only call them in instances of that class, but static methods by definition belong to the class, but since you can't call methods in an abstract class you could never call these static methods so there is no point in them being there. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
