获取 PHP imap_fetchbody正确的零件号/索引主体零件列表

Question

我很难确定如何一致地引用零件号（2.0、2.1、2.2等零件号仅指纯文本消息、图像/jpeg等的数据）。下面我将使用'1.'.$i和'2.'.$j来尝试引用给定消息中的对象。我觉得我很接近，虽然错过了什么。。。

百万美元=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=>$d1）｛//下一行，我们如何参考正确的部分，例如"'1.'.$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>';
}}}}

此外，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。当被问及相关澄清时，我很乐意完善我的问题。

在将电子邮件迁移到数据库之前，我将所有内容都附加到$email数组中。

以下是电子邮件各个部分的迭代工作原理。这里可能有一些旧的部分我不再使用了，尽管这很好。缺少的函数是我用来在将不同部分写入数据库之前准备它们的。
