<?php $values = array('1','2'); $is_multidim = (bool) count(array_filter($values, 'is_array')); var_dump($is_multidim); var_dump(isset($values[0]), $values[0]); var_dump(isset($values[0][0]), $values[0][0]);

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).
