I'd like to know if there's a technical reason of why PHP's designers decided to invoke a static method using Class::static_method() instead of Class->static_method() (like any other method). Does the syntax change reflect any technical requirement?

I'm asking this because the syntax for every single other language I know to invoke a method is always the same, despite it being static or not.

    it imitates C++ in that; it has 3 different ways to invoke methods: the dot for references and values, the arrow for pointers and the double colon for statics – ratchet freak Nov 21 '13 at 19:23
  • @ratchetfreak does that make any easier to parse the code? – Geeo Nov 21 '13 at 20:23

Invocation of instance methods is not Class->method() but $object->method(). Additionally, semantics of the -> operator is that it passes the instance of the class (vulgo: object) to the method in a hidden parameter; class methods differ from instance methods in that they, at best, have access to class attributes.
