How to get child class name from parent class

I'm trying to accomplish this without requiring a function on the child class... is this possible? I have a feeling it's not, but I really want to be sure...

<?php
class A {
    public static function who() {
        echo __CLASS__;
    }
    public static function test() {
        static::who(); // Here comes Late Static Bindings
    }
}

class B extends A {
    public static function who() {
        echo __CLASS__;
    }
}

B::test(); //returns B
?>

Use get_called_class() instead of __CLASS__. You'll also be able to replace static with self as the function will resolve the class through late binding for you:

class A {
    public static function who() {
        echo get_called_class();
    }
    public static function test() {
        self::who();
    }
}

class B extends A {}

B::test();
