<?php $ip = '192.168.21.0 - 192.168.21.255'; $ip = explode('-', $ip); list($lower, $upper) = $ip; $lower_dec = (float) sprintf("%u", ip2long($lower)); $upper_dec = (float) sprintf("%u", ip2long($upper)); print_r($lower_dec); print_r($upper_dec);

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).
