<?php class IsGet { private $arr = [1 => 1, 2 => 2, 3 => 3]; function &__get($property) { echo "__get\n"; return $this->arr; } function __isset($property) { echo "__isset\n"; return false; } } $instance = new IsGet(); var_dump(isset($instance->arr[1]));

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).
