imap-получить прикрепленный файл

как получить прикрепленный файл из этого письма?

Это письмо отправляется с компьютера apple, и электронная почта struture не похож на любой другой (сюрприз).. здесь часть с диспозицией на одно измерение глубже, чем другое..

скрипт работает с каждым другим письмом, где часть с файлом находится в первом измерении, но не с этим

$part->dparameters[0]->value возвращает имя файла, но strlen($data) возвращает 0

imap поток

$structure = imap_fetchstructure($this->stream, $this->msgno);

if(isset($structure->parts)){
    print_r($structure->parts);
    $this->parse_parts($structure->parts);
}

function parse_parts($parts){
    foreach($parts as $section => $part){
        if(isset($part->parts)){

            // some mails have one extra dimension
            $this->parse_parts($part->parts);

        }
        elseif(isset($part->disposition)){
            if(in_array(strtolower($part->disposition), array('attachment','inline'))){
                $data = imap_fetchbody($this->stream, $this->msgno, $section+1);

вы не указываете правильный номер раздела для вложенных вложений. Вам нужно передать номер раздела в рекурсивном шаге.

function parse_parts($parts, $parentsection = ""){
    foreach($parts as $subsection => $part){
        $section = $parentsection . ($subsection + 1);
        if(isset($part->parts)){

            // some mails have one extra dimension
            $this->parse_parts($part->parts, $section . "." );

        }
        elseif(isset($part->disposition)){
            if(in_array(strtolower($part->disposition), array('attachment','inline'))){
                $data = imap_fetchbody($this->stream, $this->msgno, $section );

я использовал код с этой страницы:

http://www.sitepoint.com/exploring-phps-imap-library-2/

загрузка вложений в каталог с помощью IMAP в PHP случайным образом работает


Я не знаю конкретно об электронных письмах Mac, но вот некоторый код, который у меня есть, который проходит через каждую из частей, чтобы увидеть, является ли это "вложением" и сохраняет файл где-то, чтобы я мог позвонить ему позже.

$body = imap_fetchstructure($box, $i);
$attachments = '';
$att = count($body->parts);
if($att >=2) {
for($a=0;$a<$att;$a++) {
if($body->parts[$a]->disposition == 'ATTACHMENT') {
$file = imap_base64(imap_fetchbody($box, $i, $a+1));
$string = genRandomString();
    if(!file_exists('/var/www/email_store/'.$_SESSION['site_user_id'])) {
        mkdir('/var/www/email_store/'.$_SESSION['site_user_id'].'/');   
    }
    $attachments .= $body->parts[$a]->dparameters[0]->value.'[#]'.$string.',';
    file_put_contents('/var/www/email_store/'.$_SESSION['site_user_id'].'/'.$string,$file);
    }
}
