PHP receiveMail implements the function of receiving emails

This article mainly introduces the function of receiving emails in PHP receiveMail in detail. It has a certain reference value. Interested friends can refer to it.

Using PHP to send emails, I believe you are not familiar with it. It's unfamiliar, but if you read the inbox, you will have less contact. This time I will summarize my experience and hope it can help everyone.

Note:

1.PHP mainly uses imap extension to read the inbox, so before using the following method, you must enable the support of imap extension module.

2.This method supports Chinese and will not cause garbled characters. The encoding of all files needs to be consistent

1. File structure

2.Mail class ./mailreceived/receiveMail.class.php

./mailreceived/receiveMail.class.php The file content is as follows:
