Why can't you call abstract functions from abstract classes in PHP?
- by incrediman
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
<?php
    abstract class AbstractFoo{
        abstract public static function foo();
        public static function getFoo(){
            return self::foo();//line 5
        }
    }
    class ConcreteFoo extends AbstractFoo{
        public static function foo(){
            return "bar";
        }
    }
    echo ConcreteFoo::getFoo();
?>
Error: 
  Fatal error: Cannot call abstract method AbstractFoo::foo() in foo.php  on line 5
