Use  iconv_mime_decode();



<?php

// This yields "Subject: Prüfung Prüfung"

echo iconv_mime_decode("Subject: =?UTF-8?B?UHLDvGZ1bmcgUHLDvGZ1bmc=?=",

                       0, "ISO-8859-1");

?>

That fixed the all caps issue:





<?php


function imap_utf8_fix($string) {


  return iconv_mime_decode($string,0,"UTF-8");


}


?>

{


      $newString = '';


      $elements=imap_mime_header_decode($string);


      for($i=0;$i<count($elements);$i++) 


      {


        if ($elements[$i]->charset == 'default')


          $elements[$i]->charset = 'iso-8859-1';


        $newString .= iconv($elements[$i]->charset, $charset, $elements[$i]->text);

Be aware: imap_utf8 tends to return the string in uppercase.

You may also try this example:



$_subject = "=?iso-8859-1?b?THV6b26uMTQ=?= dot CoM";

echo utf8_decode(imap_utf8($_subject));



OUTPUT: Luzon®14 dot CoM

Also see: 

<?php

imap_mime_header_decode($sting);

?>

Don't try to decode subjects with this one... imap_mime_header_decode does a much better job at that.

# this script are correct with the right signs remove expression

# please, ignore the later.

function decode_utf8($str){

       # paterns

           $err="(=\?.{10,13}q\?_?|\?\=)";

           $pat = "/=([0-9A-F]{2})/"; 

           $cha="'.chr(hexdec(";

       # erase null signs in string

          $str=eregi_replace($err,"",$str);

       # to decode with eval and replace

          eval("\$str='".

                  preg_replace($pat,$cha."'$1')).'",$str)

                  ."';");

        # return

           return $str;

} 

#Note: you can to reduce this script in 3 lines.

To get a complete decode to utf8 (which is the protocol with "national" characters), use these two:

$subject = "=?ISO-8859-1?Q?B=F8lla?=, med =?ISO-8859-1?Q?=F8l?= i baggen";

$subject = imap_utf8($subject);

$subject = utf8_decode($subject);

will return the subject in 8-bit ascii.

That is, both functions.
