Calling a static method on a class known by name?

Question

Hello!

Is there any way to obtain this effect in a PHP version prior to 5.3?

class A {
  public static function x() {print 'ok'; }
}

$className = 'A';
$className::x();

Thanks! Palantir

Answer 1

$className = 'A'; 
call_user_func(array($className,'x'));

Answer 2

call_user_func(array($className,'x'));

see http://cz.php.net/manual/en/function.call-user-func.php

Answer 3

Yes you can by using call_user_func_array :

call_user_func_array(array($className, 'x'), array()) ;
