Reference to static method in PHP?

Question

In PHP, I am able to use a normal function as a variable without problem, but I haven\'t figured out how to use a static method. Am I just missing the right syntax, or is this

Answer 1

In addition to what was said you can also use PHP's reflection capabilities:

class Bar {

    public static function foo($foo, $bar) {
        return $foo . ' ' . $bar;
    }


    public function useReferences () {
        $method = new ReflectionMethod($this, 'foo');
        // Note NULL as the first argument for a static call
        $result = $method->invoke(NULL, '123', 'xyz');
    }

}
