<?php /* declare(strict_types=1); */ $foo = new class { public function __toString () { return "foo"; } }; function bar (string $foo) { var_dump(gettype($foo), $foo); } bar($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).
