script nn salva allegati mail

[dearste]

Come da oggeto del post ho un problema nel salvare gli allegati..

questo è il codice per visualizzare gli allegati:

$structure = imap_fetchstructure($inbox, $id);

$structure=imap_fetchstructure($inbox, $id);

if(isset($structure->parts)) {

echo "<tr><td>Allegati:</td><td>";

while(list($key,$val) = each($structure->parts)) {

if($key > 0) {

if($val->ifparameters) {

$attach=$val->parameters;

echo "<a href='gotodownload.php?id=$id&part=$key' TARGET=blank>";

$attachmenttext=$attach[0]->value;

$attachmenttext=str_replace("US-ASCII", "HTML/HTM Document", $attachmenttext);

$attachmenttext=str_replace("us-ascii", "HTML/HTM Document", $attachmenttext);

echo $attachmenttext;

echo "</a>,";

} else {

echo "<a href='gotodownload.php?id=$id&part=$key' TARGET=blank>";

echo "(unnamed)</a>
";
}}
}}

if(isset($structure->parts)) {

$body=imap_fetchbody($inbox, $id,1);

} else {

$body=imap_body($inbox, $id);

}
$partone = $structure;
$parttwo = $partone->parts[0];
if($parttwo->encoding == 3) {

$ambody = imap_base64($body);
} 

e questo è gotodownload.php

$mimetype=array("text","multipart","message","application","audio","image","video","other");



$structure=imap_fetchstructure($inbox, $id);

$attach_body = imap_fetchbody($inbox, $id,$part+1);

$atype=$structure->parts[$part]->type;

if($atype=="") $atype=0;

$asubtype=$structure->parts[$part]->subtype;

if($asubtype == "") $asubtype='PLAIN';

$attach_type=$mimetype[$atype]."/".$asubtype;

$attach_name=$structure->parts[$part]->parameters[0]->value;

if($attach_name = "") $attach_name='(unnamed)';



$anencode=$structure->parts[$part]->encoding;

if($anencode == 3){

$return_content=imap_base64($attach_body);

} elseif($anencode == 4) {

$return_content=imap_qprint($attach_body);

} else {

$return_content=$attach_body;

}

header("Content-type: $attach_type");

if(($atype != 0) && ($atype != 5)){

header("Content-Disposition: attachment; filename=$attach_name");

}

echo $return_content; 

quando clikko sul link dell'allegato, mi fa salvare o aprire il file gotodownload.php, invece dell'allegato!
Avete qualche consiglio?

Grazie
