Why can't you call abstract functions from abstract classes in PHP?

Question

I\'ve set up an abstract parent class, and a concrete class which extends it. Why can the parent class not call the abstract function?

//foo.php


        

Answer 1

It's a rule that abstract and static keywords can not be use on a method at the same time.

A method with an abstract keyword means that sub-class must implement it. Adding static to a method of a class allows us to use the method without instantiating it.

So that is why the error occurs.
