PHP通过邮件接口实现邮件发送的方法

//设置SMTP参数
$mail->ISSMTP(); //使用SMTP发送邮件
$mail->Host = "smtp.example.com"; //SMTP服务器地址
$mail->SMTPAuth = true; //启用SMTP身份验证
$mail->Username = "your-email@example.com"; //发件人邮箱账号
$mail->PassWord = "your-email-password"; //发件人邮箱密码
$mail->Port = 25; //SMTP端口号（一般为25）
$mail->SMTPSecure = "tls"; //启用TLS加密

//设置收件人、发件人、邮件主题、正文
$mail->SetFrom("your-email@example.com", "Your Name"); //发件人邮箱、名称
$mail->AddAddress("recipient@example.com", "Recipient Name"); //收件人邮箱、名称
$mail->Subject = "This is the subject of the email"; //邮件主题
$mail->Msghtml("This is the message body of the email"); //邮件正文

//发送邮件
if($mail->Send()) {
    echo "The email was sent successfully";
} else {
    echo "The email could not be sent";
}
