Exactly, and since our current $x = 'hello::world'; $x(); doesn't support method calls, the array one can help on this just like the call_user_func() approach with arrays.

<?php

class Hello { static public function world($x) { echo "Hello, $x\n"; } }

function hello_world($x) { echo "Hello, $x\n"; }

$callbacks = array( array('Hello', 'world'), function ($x) { echo "Hello, $x\n"; }, 'hello_world' );

foreach ($callbacks as $k => $callback) { if (is_callable($callback)) { $callback($k); } }

Output: Hello, 0 Hello, 1 Hello, 2
