This function seems to have a bug, when the quoted-printable string contains a "=" without the HEX code of a Character.
I use the regular quoted_printable_decode instead.

If you don't have access to the imap_qprint function and you have to encode URL Decoded and Quoted Printable Strings you receive by Mail try this simple function. But if you don't receive URL Decoded data and the string doesn't contain an = you better use http://www.php.net/manual/en/function.quoted-printable-decode.php
function decode_qprint($str){
$arr= array("A","B","C","D","E","F");
while (list(, $var) = each($arr)) {
$i=0;
while ($i <=9){
$str=str_replace("=".$var.$i,"%".$var.$i,$str);
$i++;}
$arr2 = array("A","B","C","D","E","F");
while (list(, $val) = each($arr2)) {
$str=str_replace("=".$var.$val,"%".$var.$val,$str);}}
$str = urldecode($str);
$str = utf8_encode($str);
return $str;}
$s2d='=F6=D6=DF=C4=E4=DC=FC=A9=AE';
$2s2d='%F6';
$output = decode_qprint($s2d);
$output2 = decode_qprint($2s2d);
echo $output;
echo $output2;

I just got rid of the loops using a regex.
<?php
function decode_qprint($str) {
$str = preg_replace("/\=([A-F][A-F0-9])/","%$1",$str);
$str = urldecode($str);
$str = utf8_encode($str);
return $str;
}
?>
Thanks for sharing!

Some mails are encoded in bad quoted printable format:
I use this function to decode the qprint:
for($i=0;$i<256;$i++)
{
$c1=dechex($i);
if(strlen($c1)==1){$c1="0".$c1;}
$c1="=".$c1;
$myqprinta[]=$c1;
$myqprintb[]=chr($i);
}
function decode($data,$code)
{
if(!$code){return imap_utf7_decode($data);}
if($code==0){return imap_utf7_decode($data);}
if($code==1){return imap_utf8($data);}
if($code==2){return ($data);}
if($code==3){return imap_base64($data);}
if($code==4){return imap_qprint(str_replace($myqprinta,$myqprintb,($data)));}
if($code==5){return ($data);}
}
