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...)

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

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.

For those who search for a good implementation of modified UTF-7 encoding for IMAP, you can find a code that works on :
http://tananyag.ntszki.hu/mail/functions/imap_utf7_local.php
The result is different from imap-utf7-encode() function and is identical to mailbox name generated by Thunderbird.
