简单的HTML/PHP表单永远不能发送电子邮件

<?php
require 'phpmailer/PHPMailerAutoload.php';

// 创建一个新的PHPMailer实例
$mail = new PHPMailer;

// 配置SMTP服务器设置
$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;

// 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 = 'Test Email';
$mail->Body = 'This is a test email message.';

// 发送邮件
if ($mail->send()) {
    echo 'Email sent successfully.';
} else {
    echo 'Email could not be sent.';
}
?>
