Ummmm.... I made a mistake in the second test for validity in the
unpad function. It should be this:
function pkcs5_unpad ($text)
{
$pad = ord($text{strlen($text)-1});
if ($pad > strlen($text)) return false;
if (strspn($text, chr($pad), strlen($text) - $pad) != $pad) return false;
return substr($text, 0, -1 * $pad);
}
