run code in 300+ PHP versions simultaneously
<?php $iterations = 10000; class A { protected $number; public function __construct() { $this->number = rand(); } } foreach ($i = 0; $i <= $iterations; ++$i) { $someVariable = new A; }

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).
