<?php $a = 'ほげ'; $b = 'ほげ'; var_dump([ '$a===$b' => $a === $b, '$a' => bin2hex($a), '$b' => bin2hex($b), ]); /* array(3) { ["$a===$b"]=> bool(false) ["$a"]=> string(12) "e381bbe38192" ["$b"]=> string(14) "e381bb0fe38192" } */

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).
