imap_utf7_decode
Maccoy function's isn't reliable 'cause it doesn't follow the RFC 2060. It will work fine for most latin chars (which, in base64, will turn into "+A..."), but for other language it can make a big mess. If you're using an internationalizated system, try using the other presented options.
imap_utf7_encode
(PHP 4, PHP 5)
imap_utf7_encode — 8비트 데이터를 UTF-7 텍스트로 변환한다.
Description

( string $data
)
8비트 data 를 modified UTF-7텍스트로 변경한다. 이 함수는 출력가능한 아스키(ASCII)코드 범위를 벗어난 국제적인 문자를 포함하는 메일박스 이름을 인코딩할 때 필요하다. modified UTF-7 인코딩은 » RFC 2060, section 5.1.3문서에 정의되어 있다. ( original UTF-7은 » RFC1642 문서에 정의되어 있다).

This encoding will not work for cyrus imapservers and you might have problems with other mail clients.
Use mb_convert_encoding($str, "UTF7-IMAP","ISO-8859-15") instead.
ps: mb_convert_encoding() requires building php with --enable-mbstring option

Note that php4 (4.4.0) will encode IMAP folders in a way that no other program will be able to decode them back.
$ php4 <<EOF
> <?php
> echo "ENCODED: " . imap_utf7_encode("") . "\\n";
> ?>
> EOF
ENCODED: &w5w-
Now try to decode the result string ("&w5w-") using e.g. javamail or python's imaplib, or if you don't like these languages - create an IMAP folder using PHP and try to display it in an IMAP client (mutt, thunderbird, outlook, whatever...)
