<?php class Test { static public function getNew() { return new static; } } $a = new Test(); $b = new $a(); print_r($b); print_r($a) $c = new $a; var_dump($a !== $b); var_dump($a !== $c);

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).
