<?php $arr = array(1,2,3,4,5,6,7,8,9,10,'a','b','c','d','e','f','g','h','i','j'); $tmp0 = $arr[0]; $tmp1 = $arr[10]; $n=10; for($i=0,$j=n;$i<count($arr);$i+=2,$j++){ $arr[$i]=$tmp0; $tmp0 = $arr[$i+1]; $arr[$i+1]=$tmp1; $tmp1 = $arr[$j]; } for($i=0;$i<count($arr);$i++){ echo($arr[$i]." "); } ?>

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).
