<?php $array = [null, '', .0, false, null, 0, '0.0', -.1, "\0", false]; $unique = array(); foreach($array as $v){ isset($k[$v]) || ($k[$v]=1) && $unique[] = $v; } var_dump($unique);

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).
