<?php class A { function b() { static $count; if (null === $count) { $count = 1; return ['a', 'b']; } return $count++; } } $a = new A; var_dump($a->b(), $a->b()); $a = new A; var_dump($a->b()[$a->b()]);

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).
