email — php скачать почтовое вложение без функции

Я хотел бы скачать вложение с помощью PHP с адреса электронной почты на сервер, где находится скрипт PHP. Скрипт работает без сбоев, но ничего не загружается.

<?php
set_time_limit(3000);
$hostname = '{******************************}INBOX';
$username = '*****@**********.de'; # e.g somebody@gmail.com
$password = '*****************';/* try to connect */
$inbox = imap_open($hostname,$username,$password) or die('Cannot connect to Gmail: ' . imap_last_error());/* get all new emails. If set to 'ALL' instead
* of 'NEW' retrieves all the emails, but can be
* resource intensive, so the following variable,
* $max_emails, puts the limit on the number of emails downloaded.
*
*/
$emails = imap_search($inbox,'ALL');

/* useful only if the above search is set to 'ALL' */
$max_emails = 16;/* if any emails found, iterate through each email */
if($emails) {

$count = 1;

/* put the newest emails on top */
rsort($emails);

/* for every email... */
foreach($emails as $email_number)
{

/* get information specific to this email */
$overview = imap_fetch_overview($inbox,$email_number,0);

/* get mail message */
$message = imap_fetchbody($inbox,$email_number,2);

/* get mail structure */
$structure = imap_fetchstructure($inbox, $email_number);

$attachments = array();

/* if any attachments found... */
if(isset($structure->parts) && count($structure->parts))
{
for($i = 0; $i < count($structure->parts); $i++)
{
$attachments[$i] = array(
'is_attachment' => false,
'filename' => '',
'name' => '',
'attachment' => ''
);

if($structure->parts[$i]->ifdparameters)
{
foreach($structure->parts[$i]->dparameters as $object)
{
if(strtolower($object->attribute) == 'filename')
{
$attachments[$i]['is_attachment'] = true;
$attachments[$i]['filename'] = $object->value;
}
}
}

if($structure->parts[$i]->ifparameters)
{
foreach($structure->parts[$i]->parameters as $object)
{
if(strtolower($object->attribute) == 'name')
{
$attachments[$i]['is_attachment'] = true;
$attachments[$i]['name'] = $object->value;
}
}
}

if($attachments[$i]['is_attachment'])
{
$attachments[$i]['attachment'] = imap_fetchbody($inbox, $email_number, $i+1);

/* 4 = QUOTED-PRINTABLE encoding */
if($structure->parts[$i]->encoding == 3)
{
$attachments[$i]['attachment'] = base64_decode($attachments[$i]['attachment']);
}
/* 3 = BASE64 encoding */
elseif($structure->parts[$i]->encoding == 4)
{
$attachments[$i]['attachment'] = quoted_printable_decode($attachments[$i]['attachment']);
}
}
}
}

/* iterate through each attachment and save it */
foreach($attachments as $attachment)
{
if($attachment['is_attachment'] == 1)
{
$filename = $attachment['name'];
if(empty($filename)) $filename = $attachment['filename'];

if(empty($filename)) $filename = time() . ".dat";

/* prefix the email number to the filename in case two emails
* have the attachment with the same file name.
*/
$fp = fopen($filename, "w+");    // $email_number . "-" .
fwrite($fp, $attachment['attachment']);
fclose($fp);
}

}

if($count++ >= $max_emails) break;
}

}

/* close the connection */
imap_close($inbox);

echo "Done";

?>

Вложение не загружено. Сценарий связывает аккуратно. Пожалуйста, помогите мне?
