run code in 300+ PHP versions simultaneously
<?php class foo { function __construct($foo = null) { $this->foo = $foo; } public $foo = new foo; } var_dump(new foo == new foo);

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).
