That fixed the all caps issue:

<?php
function imap_utf8_fix($string) {
  return
iconv_mime_decode($string,0,"UTF-8");
}
?>

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

Use  iconv_mime_decode();

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

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.

I got issues decoding strings with spanish characters. I found encodeISO88591() function at this manual as an user note.

After having problems with imap_utf8() and utf8_decode(), I've decided create a function decodeISO88591() for decoding strings encoded with encodeISO88591().

Here's the code(I've translated remarks and variable and array names from spanish to english for better understanding):

function encodeISO88591($string)
{
  // ISO-8859-1 string header
  $stringISO = "=?iso-8859-1?q?";
 
  // Each character are encoded('equal-to' symbol + hexadecimal value from ASCII code)
  for($i=0;$i<strlen($string);$i++)
  {
    // Basic ASCII characters are not encoded
    if(ord(substr($string,$i,1))<1 || ord(substr($string,$i,1))>127)
    {
      $char = ord($string[$i]);
      $char = strtoupper(dechex($char));
      $stringISO.="=".$char;
    }
    else
    {
      $stringISO.=substr($string,$i,1);
    }
  }
 
  // ISO-8859-1 string footer
  $stringISO.="?= ";
 
  return($stringISO);
}

// And this is my function decodeISO88591()

function decodeISO88591($string)
{
  // Arrays for obtaining hexadecimal values
  // for each ISO-8859-1 charset
  $mAlfa=array("A","B","C","D","E","F");
  $mNum=array();
  for($n=0;$n<10;$n++)
  {
    $mNum[]=$n;
  }
 
  // ISO-8859-1 charset
  $iso88591=array(" ","","","","",
                         "","","","","","",
                         "","","","","","",
                         "","","","","","",
                         "","","","","","",
                         "","","","","","",
                         "","","","","","",
                         "","","","","","","",
                         "","","","","","",
                         "","","","","","",
                         "","","","","","","",
                         "","","","","","","",
                         "","","","","","","","",
                         "","","","","","","",
                         "","","","","","","");
  // Hexadecimal values array
  for($a=0;$a<sizeof($mAlfa);$a++)
  {
    for($n=0;$n<sizeof($mNum);$n++)
    {
      $mHex[]=$mAlfa[$a].$mNum[$n];
    }
    for($a2=0;$a2<sizeof($mAlfa);$a2++)
    {
      $mHex[]=$mAlfa[$a].$mAlfa[$a2];
    }
  }
 
  // ISO-8859-1 string header and footer are deleted
  $string=str_replace("=?iso-8859-1?q?","",$string);
  $string=str_replace("?= ","",$string);
 
  // Encoded values are decoded
  for($h=0;$h<sizeof($mHex);$h++)
  {
    $string=str_replace(("=".$mHex[$h]),$iso88591[$h],$string);
  }
 
  return($string);
}

I hope this helps somebody. :)
