<?php $array = array(1 => 'one', 2.5 => 'two', '3' => 'three', '4.5' => 'four', 'five' => 5); var_export(isset($array[2.5])); var_export(isset($array['3'])); var_export(isset($array[4.5]));

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).
