PHP和PHPMAILER：如何在网站中实现邮件发送的活动邀请功能？

composer require phpmailer/phpmailer

require 'vendor/autoload.php';

<?php
require 'vendor/autoload.php';

use PHPMailerPHPMailerPHPMailer;
use PHPMailerPHPMailerException;

function sendInvitation($email, $name, $activityName, $activityDate) {
    $mail = new PHPMailer(true);
    try {
        // 服务器配置
        $mail->isSMTP();                                      
        $mail->Host = 'smtp.example.com';                   
        $mail->SMTPAuth = true;                               
        $mail->Username = 'your_email@example.com';         
        $mail->Password = 'your_email_password';                               
        $mail->SMTPSecure = 'tls';                            
        $mail->Port = 587;                                   

        // 收件人和邮件内容
        $mail->setFrom('your_email@example.com', 'Your Name');
        $mail->addAddress($email, $name); 
        $mail->isHTML(true);                                  
        $mail->Subject = '邀请函 - '.$activityName;
        $mail->Body    = '尊敬的'.$name.'：<br> 您被邀请参加活动:'.$activityName.'，时间:'.$activityDate.'。详情请查看附件。';
        $mail->AltBody = '尊敬的'.$name.'： 您被邀请参加活动:'.$activityName.'，时间:'.$activityDate.'。详情请查看附件。';

        // 添加附件
        $mail->addAttachment('path/to/file.pdf');

        $mail->send();
        echo '邮件已发送';
    } catch (Exception $e) {
        echo '邮件发送失败: ' . $mail->ErrorInfo;
    }
}

// 示例用法
sendInvitation('invitee@example.com', '张三', '周末聚会', '2022-05-15');
