run code in 300+ PHP versions simultaneously
<?php class A { public $c = 0; public function A($c) { print($this->c); print($c); } } class B extends A { public function B($c) { c++; $this->c++; $_c = $this->c > 0 ? $c : -1; parent::A($c); } } $b = new B(2);

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).
