Question

我想用PHP制作pop3客户端。当我得到所有消息（正文+标题）时，我有一个问题，我想分割标题和正文。通常在标题之后有一个空行，然后有一个消息体。我意识到在我的邮箱中的一封电子邮件中有一个空白行标题：

如何将正文和标题分隔的消息与空白行分开？

Answer 1

要解析邮件消息，首先必须找到标题结束的位置。这将在消息的第一个空白行中。

一旦找到，您可能需要解析消息本身。这样做的原因是您提供了一个多部分消息，它由......多个部分组成。每个部分都可以有自己的内容类型。这对于HTML电子邮件以及带附件的电子邮件来说很常见。

要了解如何解析多部分消息，您需要查找边界标识符。这在标题的末尾概述：

Content-Type: multipart/alternative; boundary=702637934216955106

只需在边界上拆分消息，然后分别处理每个部分。
