What exactly are late static bindings in PHP? 7 answers

You use late static binding for this

Basically in the abstract class you call static::method() . This uses the method of the class that made the call.

Abstract Class A{
    public function foo(){
        // Late static binding
        static::bar();
    }

   abstract public static function bar();
}
