<?php $arr=array(1=>1,2=>2,3=>3,4=>4,5=>5,6=>6,7=>7,8=>8,9=>9,); $count=count($arr); foreach($arr as $key=>$value){ if($key%2==0){ unset($arr[$key]); $count--; } if(1!=$count) coutinue; else return $key; }

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).
