Calling a public, static function in an abstract class
I would be surprised if this wouldn't be allowed. Abstract class assumes you cannot instantiate it. As static methods don't need a class instance, you can happily use them.
Looking deeper, you could create an abstract static method and call it from your non-abstract method:
abstract class ScopeFactory{ public static function doStuff() { static::otherStuff(); } abstract public static function otherStuff();}PHP will give you a fatal error saying you cannot call an abstract method. But also it'll give you a E_STRICT warning saying you shouldn't create abstract static methods.
