php - 如何从 POP3 电子邮件中提取数据？

Question

我使用 PHP 从 POP3 服务器接收电子邮件。我有一个包含标题和正文的原始字符串。如何以类或数组的形式解析标题和正文？

我所拥有的示例:

我想做的事:

echo $from;
echo $replyTo;
echo $date;
echo $body;
echo $subject;
echo $charset;

看看 MIME E-mail message parser类。
根据作者的描述:

This class can be used to parse and decode MIME e-mail messages. It supports decoding single RFC 2822 MIME messages or archives that aggregate multiple messages in the mbox format. The decoded message data is returned as an array that describes one or more messages found in a message file or data string. The bodies of multipart messages can be decoded into distinct sub-messages. The message body data can decoded and saved to separate files, so the class can handle messages larger than the available memory.
