<?php class Foo { public $secret = 'I actually prefer coding with Go'; public function getClosure() : closure { return function() { return $this->secret; }; } public function dontLeakMyStuff() { return create_function('', 'return $this->secret;'); } } $foo = new Foo(); $closure = $foo->getClosure(); var_dump($closure()); $function = $foo->dontLeakMyStuff(); var_dump($function());

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).
