But my snippet did not use "::" within a class but outside any class. I have used it to access a method from outside the scope. Do we have different understandings of the term "static"? I thought of Java's ClassName.staticMethod(parameters); and ClassName.staticFieldName or of the C++ :: operator, Math::PI . Sorry that I can't get it, answer via PM if I'm spamming the list. What is :: good for. Was it made to access methods and fields of a parentclass that got overriden by a derived class? If that's what it was made for you should not be allowed to use the :: operator outside a derived class. If it's a real static method call in the way thats available in Java the syntax is rotten. How can a method that was called static rely on the $this object autocreation? I mean it's static, it's not allowed to work with the object $this ... Ulf
