<?php $packed = pack('a6', 'i'); // PHP 5.4 $data = "hoge" // PHP 5.5 $data = "hoge\0\0" var_dump($data = unpack('a1b/a1c', $packed)); // PHP 5.5 $data = "hoge" var_dump($data = unpack('Z6', $packed));

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).
