Question

我已经被困在这几个小时了。但基本上，我有一个收件箱，可以收到包含我想要删除的内容的电子邮件，以及附带的PDF。我想出了如何取出我想要的所有HTML，但如何保存附加的PDF？

这是我到目前为止的鳕鱼：

public function read_emails（）{ //设置用户检查

    $strUser     = "email";
    $strPassword = "passwrd";
    $delete_emails=false;

    // open
    $hMail = imap_open ("{webmail.somethingsomething.com:143/notls}INBOX", "$strUser", "$strPassword") or die("can't connect: " . imap_last_error());
    // get headers
    $aHeaders = imap_headers( $hMail );
    // get message count
    $objMail = imap_mailboxmsginfo( $hMail );
    if($objMail != NULL)
    {           
        // process messages
        for( $idxMsg = 1; $idxMsg <= $objMail->Nmsgs; $idxMsg++  )
        {
            // get header info
            $objHeader = imap_headerinfo( $hMail, $idxMsg );

            // get from object array
            $aFrom = $objHeader->from;

            // process headers
            for( $idx = 0; $idx < count($aFrom); $idx++ )
            {
                // get object
                $objData = $aFrom[ $idx ];
                // get email from
                $strEmailFrom = $objData->mailbox . "@" . $objData->host;
                //Get the subject 
                $message_subject = $objHeader->subject;
                //Get the body of the message
                $fullBody = imap_fetchbody($hMail,$idxMsg, 2);//displays full body including junk
                $bodyMessage = quoted_printable_decode($fullBody);
                //Get the msg structure 
                $message_structure = imap_fetchstructure($hMail, $idx);
                //WHAT DO I DO HERE????
            }

            // delete message
            if($delete_emails == true){
                imap_delete( $hMail, $idxMsg );
            }

        }

        // expunge deleted messages
        if($delete_emails == true){
            imap_expunge( $hMail );
        }


        //Clears the cache
        imap_gc($hMail, IMAP_GC_ELT);

    }
    // close
    imap_close( $hMail );



}

我有消息结构，如果我print_r我可以看到其中一个部分有附件，我可以看到它是一个PDF。不知道接下来会发生什么。我已经尝试过，似乎无法找到一个好的解决方案。

谢谢！

编辑：这是imap_fetchstructure的内容

根据doc，您在$message_structure->parts中有一系列正文部分，因此您可以遍历此数组，并在部分的->type和->subtype对应时停止到PDF文件。类似的东西：

foreach ($message_structure->parts as $idx => $part) {
    if (TYPEAPPLICATION === $part->type && 'pdf' === strtolower($part->subtype)) {
        $data = imap_fetchbody($hMail, $idxMsg, $idx);
        // Then you should check the $part->encoding
        // to decode data appropriately, e.g.:
        if (ENCBASE64 === $part->encoding) {
            $data = base64_decode($data);
        }
    }
}
