PHP : Function Reference : IMAP, POP3 and NNTP Functions : imap_mime_header

Example 1056. 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:

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.

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.

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; }

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; }

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.

<?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]); } ?>
