Кто поможет переписать функцию с js в php?

Я помогу:

http://php.net/manual/ru/book.iconv.php
http://php.net/manual/ru/function.base64-encode.php
http://php.net/manual/ru/function.base64-decode.php

В JS до настоящего времени не было подобных возможностей, вот и приходилось писать портянки, а в РНР то зачем этот мусор?
