require 'path/to/PHPMailer/src/PHPMailer.php';
require 'path/to/PHPMailer/src/SMTP.php';
require 'path/to/PHPMailer/src/Exception.php';

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\Exception;

$mail = new PHPMailer(true);

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->SMTPSecure = 'tls';
    $mail->Port = 587;

    // 设置发件人和收件人
    $mail->setFrom('your_email@example.com', 'Your Name');
    $mail->addAddress('recipient@example.com', 'Recipient Name');

    // 设置邮件主题和内容
    $mail->Subject = 'Excel File';
    $mail->Body = 'Please find the attached Excel file.';

    // 添加附件
    $attachmentPath = 'path/to/your/excel/file.xlsx';
    $mail->addAttachment($attachmentPath);

    // 发送邮件
    $mail->send();
    echo 'Email sent successfully!';
} catch (Exception $e) {
    echo 'Email could not be sent. Error: ', $mail->ErrorInfo;
}
