Try the code in this thread if it works on you.

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') 
                        {

                        }
                    }
                }

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

                    /* 3 = BASE64 encoding */
                    if($structure->parts[$i]->encoding == 3) 
                    { 
                        $attachments[$i]['attachment'] = base64_decode($attachments[$i]['attachment']);
                    }
                    /* 4 = QUOTED-PRINTABLE 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("./" . $email_number . "-" . $filename, "w+");
                fwrite($fp, $attachment['attachment']);
                fclose($fp);
            }

        }

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

} 

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

echo "Done";
