如何从电子邮件中获得附加的PDF并保存它，php

Question

我一直坚持了几个小时。但基本上，我有一个收件箱，可以发送带有一些我想要取出的内容的电子邮件，以及附带的PDF。我想出了如何将所有HTML都取出来，但我如何保存附加的PDF？

这是我鳕迄今为止：

公共函数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，如果我的print_r，我可以看到其中一个部分有附件，我可以看到它是PDF。不知道接下来会发生什么。我试过了，似乎无法找到一个好的解决方案。

谢谢！

编辑：这是imap_fetchstructure

按照doc，你的身体部位的数组中$message_structure->parts，所以你可以遍历这个数组，并停止在部分的->type和->subtype对应PDF文档。就像：

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); 
     } 
    } 
}
