<?php $a = array(); for ($i = 0; $i < 10000; $i++) { $a[$i] = 1; } $start = microtime(true); $count = count($a); for ($i = 0; $i < $count; $i++) {} echo "Completed in ", microtime(true) - $start, " Seconds\n"; $start = microtime(true); foreach ($a as $k => $v) {} echo "Completed in ", microtime(true) - $start, " Seconds\n"; $start = microtime(true); foreach ($a as $k => &$v) {} echo "Completed in ", microtime(true) - $start, " Seconds\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).
