run code in 300+ PHP versions simultaneously
<?php class a { function test() { print 123; } } class b extends a { function __construct() { return $this; } } (new a())->test(); new b()->test();

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).
