Accessing static methods using a variable class name PHP

Questions

I am trying to access a static method, but using a variable as the class name. Is this possible? I seem to be having issues with it. I want to be able to do something like this:

class foo {
    public static function bar() {
        echo  test ;
    }
}

$variable_class_name =  foo ;
$variable_class_name::bar();

And I want to be able to do similar using static variables as well.

That syntax is only supported in PHP 5.3 and later. Previous versions don t understand that syntax, hence your parse error (T_PAAMAYIM_NEKUDOTAYIM refers to the :: operator).

In previous versions you can try call_user_func(), passing it an array containing the class name and its method name:

$variable_class_name =  foo ;
call_user_func(array($variable_class_name,  bar ));
