PHP IMAP extract mail attachment in gmail - php

Question

I am trying to extract the attachment of an email, its structure is as follows:
stdClass Object ( [type] => 3 [encoding] => 3 [ifsubtype] => 1 [subtype] => PDF [ifdescription] => 1 [description] => 3002024147 [ifid] => 0 [bytes] => 90256 [ifdisposition] => 0 [ifdparameters] => 0 [ifparameters] => 1 [parameters] => Array ( [0] => stdClass Object ( [attribute] => NAME [value] => 3002024147.pdf ) ) )
I have tried in the following way:
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";
$fp = fopen($email_number . "-" . $filename, "w+");
fwrite($fp, $attachment['attachment']);
fclose($fp);
}
}
}
I manage to extract the email attachment that I send from Apple Mail and others, but the ones I receive with the previous structure do not.
What I can do?
