PHP - forward_static_call()

The forward_static_call() function can call a static method.

Syntax

mixed forward_static_call( callable $function [, mixed $parameter [, mixed $... ]] )

The forward_static_call() function can call a user-defined function or method given by the function parameter. It must be called within a method context and can't be used outside a class. It can use the late static binding.

Example

<?php
   class Beer {
      const NAME = 'Beer!';
      public static function printed(){
         echo 'static Beer:NAME = '. static::NAME . "\n";
      }
   }

   class Ale extends Beer {
      const NAME = 'Ale!';
      public static function printed(){
         forward_static_call(array('parent','printed'));
         call_user_func(array('parent','printed'));

         forward_static_call(array('Beer','printed'));
         call_user_func(array('Beer','printed'));
       }
   }
   Ale::printed();
   echo "\n";
?>

Output

static Beer:NAME = Ale!
static Beer:NAME = Ale!
static Beer:NAME = Ale!
static Beer:NAME = Beer!
