<?php $cases = array(false, 0, 1, 2, 3, 4, 5, true, null); $result = array(); $s = microtime(true); foreach ($cases as $c) { $result['case_' . json_encode($c)] = !!$c; } var_dump('time : ' . (microtime(true) - $s) . ' for !!$c, result:', $result); $s = microtime(true); foreach ($cases as $c) { $result['case_' . json_encode($c)] = (bool)$c; } var_dump('time : ' . (microtime(true) - $s) . ' for (bool)$c, result:', $result);

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).
