How to use PHP Developer City to realize the quick registration function of user mobile phone numbers

With the increasing prosperity of the e-commerce market, more and more merchants are beginning to realize the importance of opening an e-commerce platform. As one of the core functions of the e-commerce platform, the user registration function has become the focus of merchants' attention and efforts to improve. In this information age, the quick registration function of user mobile phone numbers is widely used in various websites and applications. User information can be quickly obtained through mobile phone number registration, saving users time and operation steps. So, how to use PHP Developer City to realize the quick registration function of user mobile phone number? Here is a common implementation method introduced to you.

Step 1: Create a database table

Before developing the city platform, we need to create a user table to store user-related information, including user ID, mobile phone number, user name, Password etc. It can be created using a MySQL database. The following is a commonly used table structure design:

CREATE TABLE `users` ( `id` int(11) NOT NULL AUTO_INCREMENT, `mobile` varchar(20) NOT NULL, `username` varchar(50) NOT NULL, `password` varchar(100) NOT NULL, `created_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, PRIMARY KEY (`id`), UNIQUE KEY `mobile` (`mobile`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Step 2: Front-end mobile phone number verification

On the front-end of the user registration page, we need to add a mobile phone number number input box, and perform real-time verification of the mobile phone number entered by the user. You can use JavaScript/jQuery to write verification logic. The following is a simple example:

Step 3: Back-end mobile phone number verification

In the previous step of front-end mobile phone number verification, we An asynchronous request is used to verify the registration status of the mobile phone number with the server. Next, we need to write a PHP script to handle this request. The following is a simple example:

prepare($query); $stmt->bind_param('s', $mobile); $stmt->execute(); $stmt->bind_result($count); $stmt->fetch(); $stmt->close(); // 返回结果给前端 if ($count == 0) { echo '0'; // 手机号未注册 } else { echo '1'; // 手机号已注册 } ?>

Step 4: Process user registration request

After the front-end mobile phone number is verified, the user clicks the registration button to trigger a registration request. We need to write a PHP script that handles registration requests. The following is a simple example:

prepare($query); $stmt->bind_param('ss', $mobile, $password); $stmt->execute(); $stmt->close(); // 返回注册成功结果给前端 echo '注册成功'; ?>

Through the above steps, we can use the PHP Developer City to realize the quick registration function of user mobile phone numbers. When the user enters the mobile phone number, the front end will verify in real time whether the mobile phone number has been registered, and the user can quickly complete the registration. At the same time, we also need to pay attention to protecting the security of users' personal information. We can increase security by encrypting and storing passwords.
