<?php $array = ("Item1.10", "Item2.5", "Item3.0", "Item2.2", "Item4.50", "Item2.50"); $tempArray = array(); $newArray = array(); foreach($array as $value) { $item = substr($value, 0, 5); if(!in_array($item, $tempArray)) { $newArray[] = $value; $tempArray[] = $item; } } print_r($newArray);

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).
