-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 The reason 'abstract static' makes no sense is because static methods are bound to the class they are defined in. Inheritance rules do not apply. Therefore a static method that is defined abstract would theoretically never be able to be implemented. A method defined in a derived class with the same name would not be implementing it but would simply be a static method on another class that happens to have the same name. I really don't mind if this is allowed or not, but I feel that while one of the niceties of PHP is it's flexibility, OO theory still needs some representation.
