PHP Mobile Phone Authentication Login Registration Implementation Guide

In the era of mobile Internet, mobile phone authentication has become a commonly used security measure. In the login and registration process of the website, mobile phone verification can effectively prevent malicious registration and login behaviors and improve the security of user accounts. This article will introduce how to use the PHP programming language to implement mobile phone verification login and registration functions, and give corresponding code examples.

1. Preparation

First of all, we need a third-party SMS service provider that supports the SMS verification code function, such as Yunpian.com, Alibaba Cloud SMS, etc. Register and obtain relevant API keys and SMS templates.

2. Registration process

2.1 Mobile phone number registration form

In the registration page, add a mobile phone number input box and a button to obtain the verification code . After the user enters their mobile phone number, click the Get Verification Code button to send an SMS verification code to the user's mobile phone.

<form action="register.php" method="post">
  <input type="text" name="phone" placeholder="请输入手机号码" required>
  <button type="button" id="btn-send-code">获取验证码</button>
  <input type="text" name="code" placeholder="请输入验证码" required>
  <input type="submit" value="注册">
</form>

2.2 Send verification code

Set a button click event, and send the verification code SMS by calling the SMS service provider's API on the backend. At the same time, the verification code is saved in the Session for subsequent verification.

$(function() {
  $('#btn-send-code').click(function() {
    var phone = $('input[name="phone"]').val();
    $.ajax({
      url: 'send_code.php',
      type: 'POST',
      data: { phone: phone },
      success: function(response) {
        console.log(response);
      }
    });
  });
});

// send_code.php
$phone = $_POST['phone'];
// 调用短信发送API发送短信验证码
$result = send_sms_code($phone, $code); // 自行实现send_sms_code函数
if ($result['code'] == 200) {
  $_SESSION['sms_code'] = $code;
  echo '发送成功';
} else {
  echo '发送失败';
}

2.3 Registration logic

After the user enters the mobile phone number and verification code, click the registration button to submit the form. The backend verifies whether the mobile phone number and verification code match, and performs corresponding operations, such as writing user information to the database.

// register.php
$phone = $_POST['phone'];
$code = $_POST['code'];

if ($code == $_SESSION['sms_code']) {
  // 验证码匹配成功，进行注册操作
  // ...
  echo '注册成功';
} else {
  echo '验证码错误';
}

3. Login process

3.1 Mobile phone number login form

In the login page, add a mobile phone number input box and a verification code button. After the user enters their mobile phone number, click the Get Verification Code button to send an SMS verification code to the user's mobile phone.

<form action="login.php" method="post">
  <input type="text" name="phone" placeholder="请输入手机号码" required>
  <button type="button" id="btn-send-code">获取验证码</button>
  <input type="text" name="code" placeholder="请输入验证码" required>
  <input type="submit" value="登录">
</form>

3.2 Sending a verification code

is similar to sending a verification code in the registration process.

3.3 Login logic

After the user enters the mobile phone number and verification code, click the login button to submit the form. The backend verifies whether the mobile phone number and verification code match, and performs corresponding operations, such as verifying login through user information query database.

// login.php
$phone = $_POST['phone'];
$code = $_POST['code'];

if ($code == $_SESSION['sms_code']) {
  // 验证码匹配成功，进行登录操作
  // ...
  echo '登录成功';
} else {
  echo '验证码错误';
}

4. Summary

Through the above steps, we use the PHP programming language to implement the mobile phone verification login and registration functions. Through mobile phone SMS verification codes, the security of user accounts can be improved and malicious registration and login behaviors can be prevented. At the same time, we also learned how to call the API of a third-party SMS service provider to send SMS verification codes, and how to use Session to save verification codes and other functions. I hope this article can bring you some help.
