php - 获取 PHP 的 imap_fetchbody 正确的部分编号/索引正文部分列表

Question

我很难确定如何始终如一地引用零件编号(诸如 2.0、2.1、2.2 等的零件编号仅指纯文本/文本消息、图像/jpeg 等的数据)。下面我使用'1.'.$i和 '2.'.$j试图引用给定消息中的对象。我觉得我很接近虽然错过了一些东西......

$mbox = imap_open('{mail.example.com:143/novalidate-cert}INBOX','someone+example.com','password');

if ($mbox) { $structure = imap_fetchstructure($mbox,$message_id);

$i = 0; $j = 0;

foreach ($structure->parts as $k1 => $d1) {//Next line, how do we refer to the part correct, e.g. "'1.'.$i"?

if (isset($d1->parts))
{
 foreach ($d1->parts as $j2 => $d2)
 {//Next line, how do we refer to the part correct, e.g. "'2.'.$j"?
  $a = print_r(imap_fetchbody($mbox,$cms->page2,'2.'.$j),1);
  echo '<div><img alt="" src="data:image/jpeg;base64,'.$a.'" /></div>';
}}}}

另外我对使用任何框架都不感兴趣，我想自己弄清楚如何做到这一点。当被问及相关说明时，我很乐意完善我的问题。

在将电子邮件迁移到数据库之前，我将所有内容附加到 $email大批。

以下是电子邮件各个部分的迭代是如何工作的。这里可能有一些我不再使用的旧位，尽管这很好用。缺失函数是我用来在写入数据库之前准备不同部分的函数。

   $message = imap_body($mbox,$i);
   $structure = imap_fetchstructure($mbox,$i);

   $f = array('!');
   $r = array('');
   $message = str_ireplace($f,$r,$message);
   $find = array('=00');
   $replace = array('');
   $message = str_ireplace($find,$replace,$message);
   $message = mb_convert_encoding($message,'us-ascii','UTF-8');
   $message = utf8_encode($message);
