imap_mime_header

Description

array imap_mime_header_decode ( string text )

imap_mime_header_decode() function decodes MIME message header extensions that are non ASCII text (see RFC2047) 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".

例子 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"; } ?>

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.

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 Mller 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;


}
