imap_mailboxmsginfo
The example of diego is working well, he has a (very) little
mistake in his code. Here is the corrected version:
<?php
//return supported encodings in lowercase.
function mb_list_lowerencodings() { $r=mb_list_encodings();
for ($n=sizeOf($r); $n--; ) { $r[$n]=strtolower($r[$n]); } return $r;
}
// Receive a string with a mail header and returns it
// decoded to a specified charset.
// If the charset specified into a piece of text from header
// isn't supported by "mb", the "fallbackCharset" will be
// used to try to decode it.
function decodeMimeString($mimeStr, $inputCharset='utf-8', $targetCharset='utf-8', $fallbackCharset='iso-8859-1') {
$encodings=mb_list_lowerencodings();
$inputCharset=strtolower($inputCharset);
$targetCharset=strtolower($targetCharset);
$fallbackCharset=strtolower($fallbackCharset);
$decodedStr='';
$mimeStrs=imap_mime_header_decode($mimeStr);
for ($n=sizeOf($mimeStrs), $i=0; $i<$n; $i++) {
$mimeStr=$mimeStrs[$i];
$mimeStr->charset=strtolower($mimeStr->charset);
if (($mimeStr == 'default' && $inputCharset == $targetCharset)
|| $mimStr->charset == $targetCharset) {
$decodedStr.=$mimStr->text;
} else {
$decodedStr.=mb_convert_encoding(
$mimeStr->text, $targetCharset,
(in_array($mimeStr->charset, $encodings) ?
$mimeStr->charset : $fallbackCharset)
)
);
}
} return $decodedStr;
}
?>
imap_mime_header_decode
(PHP 4, PHP 5)
imap_mime_header_decode — Decode MIME header elements
Description
array imap_mime_header_decode
( string $text
)
Decodes MIME message header extensions that are non ASCII text (see » RFC2047).
Parameters
- text
-
The MIME text
Return Values
The decoded elements are returned in an array of objects, where each object has two properties, charset and text.
If the element hasn't been encoded, and in other words is in plain US-ASCII, the charset property of that element is set to default.
Examples
Example #1 imap_mime_header_decode() example
<?php
$text = "=?ISO-8859-1?Q?Keld_J=F8rn_Simonsen?= <keld@example.com>";
$elements = imap_mime_header_decode($text);
for ($i=0; $i<count($elements); $i++) {
echo "Charset: {$elements[$i]->charset}\n";
echo "Text: {$elements[$i]->text}\n\n";
}
?>
The above example will output:
Charset: ISO-8859-1 Text: Keld Jørn Simonsen Charset: default Text: <keld@example.com>
In the above example we would have two elements, whereas the first element had previously been encoded with ISO-8859-1, and the second element would be plain US-ASCII.

The previous comment (from hans) seems to make no sense at all, since it will not change the encoding and possibly result in a "multiencoding" string (that the browser and anything else will be unable to render, of course).
I use a little function to decode the whole header to a specified encoding. It is as follow:
<?php
//return supported encodings in lowercase.
function mb_list_lowerencodings() { $r=mb_list_encodings();
for ($n=sizeOf($r); $n--; ) { $r[$n]=strtolower($r[$n]); } return $r;
}
// Receive a string with a mail header and returns it
// decoded to a specified charset.
// If the charset specified into a piece of text from header
// isn't supported by "mb", the "fallbackCharset" will be
// used to try to decode it.
function decodeMimeString($mimeStr, $inputCharset='utf-8', $targetCharset='utf-8', $fallbackCharset='iso-8859-1') {
$encodings=mb_list_lowerencodings();
$inputCharset=strtolower($inputCharset);
$targetCharset=strtolower($targetCharset);
$fallbackCharset=strtolower($fallbackCharset);
$decodedStr='';
$mimeStrs=imap_mime_header_decode($mimeStr);
for ($n=sizeOf($mimeStrs), $i=0; $i<$n; $i++) {
$mimeStr=$mimeStrs[$i];
$mimeStr->charset=strtolower($mimeStr->charset);
if (($mimeStr == 'default' && $inputCharset == $targetCharset)
|| $mimStr->charset == $targetCharset) {
$decodedStr.=$mimStr->text;
} else {
$decodedStr.=mb_convert_encoding(
$mimeStr->text, $targetCharset,
(in_array($mimeStr->charset, $encodings) ?
$mimeStr->charset : $fallbackCharset)
)
);
}
} return $decodedStr;
}
?>
Hope it helps.

This is obvious, but nevertheless here is a "flat" version:
<?php
private function flatMimeDecode($string) {
$array = imap_mime_header_decode($string);
$str = "";
foreach ($array as $key => $part) {
$str .= $part->text;
}
return $str;
}
?>

In response to Sven dot Dickert at planb dot de: if you encounter problems with "=?utf-8?Q?" appearing in your headers, I found that simply using "imap_utf8($string)" decoded the "$string" properly and solved my problem perfectly.

<?php
function decode_iso88591($string){
if (strpos(strtolower($string), '=?iso-8859-1') === false) {
return $string;
}
$string = explode('?', $string);
return strtolower($string[2]) == 'q' ? quoted_printable_decode($string[3]) : base64_decode($string[3]);
}
?>

This function does not code a-z 0-9 like the function posted by bandpay at hotmail dot com
function encode_iso88591($string) {
if( ereg("[^A-Za-z0-9\ ]", $string) ) {
$text = "=?iso-8859-1?q?";
for( $i = 0 ; $i < strlen($string) ; $i++ ) {
if( ereg("[^A-Za-z0-9]", $string[$i]) ) {
$text .= "=".dechex(ord($string[$i]));
} else {
$text .= $string[$i];
}
}
return $text."?=";
} else return $string;
}

imap_mime_header_decode, utf-7 and utf-8 problem, i solved the problem using below function. note that iconv function for code converting.
you must replace "EUC-KR" as iconv parameter with charset you want such as "iso-8859-1".
function mime_decode($s) {
$elements = imap_mime_header_decode($s);
for($i = 0;$i < count($elements);$i++) {
$charset = $elements[$i]->charset;
$text =$elements[$i]->text;
if(!strcasecmp($charset, "utf-8") ||
!strcasecmp($charset, "utf-7"))
{
$text = iconv($charset, "EUC-KR", $text);
}
$decoded = $decoded . $text;
}
return $decoded;
}

Beware! imap_mime_header_decode in 4.0.6 is _not_ RFC2047 conform. The string =?utf-7?Q?Petra_M+APw-ller?= will not converted into Petra Müller cause the charset utf7 is unknown. Same goes to =?utf-8?Q?Petra_M=C3=BCller?= for charset utf8.

I wrote a simple ks_c_5601-1987(2byte)
encode
function encode_ksc5601( $string )
{
$encode = base64_encode( $string );
$text = "=?ks_c_5601-1987?B?";
$text = $text.$encode."?=";
return $text;
}
