run code in 300+ PHP versions simultaneously
<?php class Foo { public function __invoke($a, $b) { echo "$a - $b\n"; } } class Bar { public $f; public function __construct() { $this->f = new Foo; } } $b = new Bar; $f = $b->f; $b->f('hello', 'world'); call_user_func($b->f, 'hello', 'world'); // i assume php assumes that f is a method here, // so this fails! Bar::f() does not exist... // $b->f('hello', 'world'); // php simply cannot parse this for whatever // reason. seems like it shoudl be able to. :) // ($b->f)('hello', 'world');

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).
