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.

Here's my new better function... ;)
function decode_ISO88591($string)
{
$string=str_replace("=?iso-8859-1?q?","",$string);
$string=str_replace("=?iso-8859-1?Q?","",$string);
$string=str_replace("?=","",$string);
$charHex=array("0","1","2","3","4","5","6","7",
"8","9","A","B","C","D","E","F");
for($z=0;$z<sizeof($charHex);$z++)
{
for($i=0;$i<sizeof($charHex);$i++)
{
$string=str_replace(("=".($charHex[$z].$charHex[$i])),
chr(hexdec($charHex[$z].$charHex[$i])),
$string);
}
}
return($string);
}
Hope this helps. :)

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. :)

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.
