run code in 300+ PHP versions simultaneously
<?php class Foo { public function doFoo(string $s = null, string ...$j) { } } class Bar extends Foo { public function doFoo(string $s = null) { } }

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).
