<?php $arr = array("one", "two", "three"); reset($arr); foreach($arr as &$v){ $v .= "_clgt?"; } //var_dump($arr); //unset($v); $v = &$c; foreach($arr as $k => $v){ echo $k . " > " . $v; }

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).
