<?php $NaN = sqrt(-1); var_dump($NaN === $NaN); var_dump(array($NaN) === array($NaN)); $a = array($NaN); $b = $a; var_dump($a === $b); reset($b); var_dump($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).
