PHP and PHPMAILER: How to implement mass mailing function in the website?

Overview:
With the development of the Internet, email has become one of the important ways for people to communicate and communicate. In website development, we often need to implement mass email functions to send large amounts of emails, such as news subscriptions, event notifications, etc. This article will introduce how to use PHP and PHPMailer to implement mass email functionality.

1. Introduction to PHPMailer:
   PHPMailer is a PHP-encapsulated email sending class library that can easily send and manage emails. It provides many advanced functions for sending emails. It can send emails through SMTP or PHP's mail() function, and supports HTML emails, attachments, SMTP authentication and other functions.
2. Preparation work:
   In order to use PHPMailer, you first need to download the latest version of PHPMailer and unzip the file. Copy the PHPMailer.php, SMTP.php and Exception.php files from the PHPMailer folder to your project directory.
3. Sample code for mass mailing:
   The following is a sample code for using PHPMailer to implement mass mailing:

<?php
require 'PHPMailer.php';
require 'SMTP.php';
require 'Exception.php';

use PHPMailerPHPMailerPHPMailer;
use PHPMailerPHPMailerException;

// 邮件发送函数
function sendEmail($to, $subject, $body) {
    $mail = new PHPMailer(true); // 实例化PHPMailer类
    try {
        // 配置SMTP服务器
        $mail->isSMTP();
        $mail->Host = 'smtp.example.com';
        $mail->SMTPAuth = true;
        $mail->Username = 'your_email@example.com';
        $mail->Password = 'your_email_password';
        $mail->Port = 587;
        
        // 配置发件人和收件人
        $mail->setFrom('your_email@example.com', 'Your Name');
        $mail->addAddress($to);
        
        // 配置邮件内容
        $mail->isHTML(true);
        $mail->Subject = $subject;
        $mail->Body = $body;
        
        // 发送邮件
        $mail->send();
        echo '邮件发送成功！';
    } catch (Exception $e) {
        echo '邮件发送失败：' . $mail->ErrorInfo;
    }
}

// 读取收件人列表
$recipients = file('recipients.txt', FILE_IGNORE_NEW_LINES);

// 发送邮件给每个收件人
foreach ($recipients as $recipient) {
    $to = trim($recipient);
    $subject = '邮件标题';
    $body = '邮件内容';
    sendEmail($to, $subject, $body);
}
?>

4. Instructions:
   ## in the above code The #sendEmail() function is the core code for sending emails. It sends emails by configuring the SMTP server, sender, recipient and email content. You need to modify the corresponding configuration parameters according to your own needs, including SMTP server address, sender email address and password.

The recipient list can be stored in a text file, with one email address per line. In the code, the file is read through the

file() function, and the email is sent to each recipient using a foreach loop.

Conclusion:
5. Through the combination of PHP and PHPMailer, we can easily implement the mass mailing function. PHPMailer provides a convenient interface and advanced functions, allowing us to control the sending and management of emails more flexibly. In actual projects, please pay attention to protecting the security of the mail server and avoid abusing the mail sending function.
