<?php class Foo { protected $func; public function __construct() { $this->func = function() { echo 'foo'; }; } public function doIt() { $a = 'func'; $this->$a(); } } $Foo = new Foo(); $callback = array($Foo, 'doIt'); $callback();

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
