run code in 300+ PHP versions simultaneously
<?php class A { public $a = 'A'; } class B { public $a; } $b = new B(); $b->a = new A(); var_dump($b);

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).
