That fixed the all caps issue:


<?php

function imap_utf8_fix($string) {

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

}

?>

Use  iconv_mime_decode();

<?php
// This yields "Subject: Prüfung Prüfung"
echo iconv_mime_decode("Subject: =?UTF-8?B?UHLDvGZ1bmcgUHLDvGZ1bmc=?=",
                       0, "ISO-8859-1");
?>

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

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

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.

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.
