<?php class App { public static $classes = array(); public function register($name, Callable $generator) { var_dump($this::$classes); exit; //$this::classes[$name] = $generator; } public function make($name) { /*if (!isset($this::classes[$name])) { throw new Exception('Invalid class name'); } */ //return $this::classes[$name](); } } $app = new App; // Internal declaration class Foo { public static function bar() { return 'static'; } } $app->register('foo', function() { return new Foo; }); // Internal Usage class SomeController { public function view() { $app = new App; echo $app->make('foo')->bar(); } } // Some extending application class MyFoo extends Foo { public static function bar() { return 'can\'t make internal methods use this.'; } } $app->register('foo', function() { return new MyFoo; }); $c = new SomeController; $c->view();

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).
