<?php $a = array(1,2,3); if (!is_null($a) && is_array($a)) { throw new Exception('The names of required fields must be an array, even if only one field is required.'); } else { echo "The if clause was not run"; } /* echo isset($a)?'true':'false'; */

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).
