It calls a class method statically, although its exact behavior depends on the
scope from which it was called. If called from outside a class, then the method
has no instanciated object, it's just a function.
This is also how you can use work with inheritance in PHP. If you have an
instanciated subclass, you can use parent::blah() to call the inherited (and
overridden) methods.
