Address of PHPMailer project: PHPMailer uses git command to clone to the local area, or directly click "Download ZIP" at the lower right of the project page to obtain the complete PHPMailer code package, and then decompress it locally.

Step 1: Enable our QQ mailbox to send mail.

How can I say that I can send mail here? In fact, all our mailboxes can send emails, but if we want to send emails in our website, we must set up our QQ mailbox, because our website now exists as a third-party client.

Step 1: Enable our QQ mailbox to send mail. In fact, all our mailboxes can send emails, but if we want to send emails in our website, we must set up our QQ mailbox, because our website now exists as a third-party client.

Since we will use SMTP server to send it later, it is suggested to open the first two items here! When you click Open, it will prompt:

When you complete the above steps, you will get an authorization code. You can copy it first, and we will use it later (if you open two items, you will get two authorization codes, and use the last authorization code! Or click the generate authorization code below to get a new authorization code, which must be the latest! )。

Step 2: Enable our php to use qq mailbox to send mail. PHPMailer needs socket extension support of PHP, while PHPMailer needs ssl encryption when linking QQ domain mailbox, and fixed PHP needs openssl support, so you can check phpinfo. If the following two items exist, you can use them regardless of the openssl version number; Many Php in virtual hosts don't support openssl extensions, and you may be miserable.

Step 3: do some processing on PHPMailer. Because there are many files in the PHPMailer folder we downloaded, we don't need them, so we don't need to waste these memories. We can streamline this folder. I only keep the following documents here: class.phpmailer.php, class.phpmaileroauth.php, class.pop3.php, class.smtp.php and PHPMailerAutoload.php.
