<?php $result = ""; echo chr(1); for ($t=0; $t<128; $t++) $result .= chr($t); echo "strlen = ".strlen($result)."\n"; echo "Result = ".$result."\n";

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).
