run code in 300+ PHP versions simultaneously
<?php $x = new __PHP_Incomplete_Class(); var_dump(is_object($x)); class Foo extends __PHP_Incomplete_Class { } $y = new Foo(); var_dump(is_object($y));

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).
