How to send SMS verification code and email notification when user registers in PHP

In the user registration function, in order to improve security and user experience, it is often necessary to Send SMS verification code and email notification to confirm the user's registration information. This article will introduce how to implement these two functions in PHP and provide sample code.

1. Send SMS verification code

Sending SMS verification code can be achieved by using the interface of the SMS platform. The following is a sample code for sending a mobile phone SMS verification code:

// 引入短信平台的SDK文件
require_once 'path/to/sms-dk/sdk.php';

// 设置短信平台的账号和密码
$account = 'your_account';
$password = 'your_password';

// 初始化短信平台的SDK对象
$sms = new SDK($account, $password);

// 生成随机的验证码
$code = mt_rand(100000, 999999);

// 将验证码保存到用户的会话中，以便验证注册时的输入
$_SESSION['sms_code'] = $code;

// 设置短信内容
$message = "您的验证码是：{$code}";

// 设置短信接收号码
$mobile = $_POST['phone'];

// 调用短信平台的发送短信方法
$result = $sms->sendSMS($mobile, $message);

if($result['code'] === '200'){
    echo "验证码已发送至手机，请注意查收！";
} else {
    echo "短信发送失败，请稍后再试！";
}

In the above code, you first need to introduce the SDK file of the SMS platform into the project and set the account and password of the SMS platform. Then, the verification code is sent to the mobile phone number entered by the user by calling the SMS sending method of the SMS platform. After sending successfully, the user can be prompted that the verification code has been sent.

2. Send email notification

Sending email notification can be achieved by using SMTP protocol. The following is a sample code for sending email notifications:

// 引入邮件发送类库
require_once 'path/to/phpmailer/class.phpmailer.php';

// 实例化一个邮件发送对象
$mail = new PHPMailer();

// 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_password';

// 配置邮件内容
$mail->SetFrom('your_email@example.com', 'Your Name');
$mail->AddAddress($_POST['email']);
$mail->Subject = "用户注册通知";
$mail->Body = "尊敬的用户，您已成功注册！";

// 发送邮件
if($mail->Send()){
    echo "邮件已发送，请注意查收！";
} else {
    echo "邮件发送失败，请稍后再试！";
}

In the above code, you first need to introduce the email sending class library into the project, and configure the SMTP server information as needed, including the SMTP server domain name, user name and password . Then, instantiate an email sending object and configure the content of the email, and finally call the Send() method to send the email. After sending successfully, the user can be prompted that the email has been sent.

Summary:

By using the SMS platform interface and SMTP protocol, we can implement the function of sending mobile phone SMS verification codes and email notifications when users register. The above code provides sample code, which can be adjusted and expanded accordingly according to actual project needs. At the same time, ensure that you comply with the relevant service agreement and privacy policy when using the SMS platform or SMTP server.
