How to use PHP Developer City to implement user account security setting function

With the continuous development of e-commerce, mall websites have become the main channel for people to shop. In order to protect users' account security, mall websites need to provide complete account security settings. This article will introduce how to use the PHP Developer City to implement user account security settings.

1. User registration and login function
Users first need to register on the mall website and set an initial password for their account. When a user registers, legality verification should be performed to ensure that user name, password and other information meet the requirements. When a user logs in, the correctness of the user's username and password should be verified. You can use the password hash function provided by PHP to encrypt and store user passwords to improve password security.

2. Password retrieval function
If the user forgets his password, the mall website should provide a password retrieval function. When the user enters their username or registered email address, the mall website should send the user an email containing a password reset link. When the user clicks on the link, they can set a new password to log in.

3. Password change function
The mall website should provide users with the function of changing passwords so that users can change their passwords when necessary. When users change their password, they need to first verify the correctness of their original password, and then enter a new password to change it. When changing the password, you can use the password hash function provided by PHP to encrypt and store the new password.

4. Binding mobile phone and email function
The mall website should provide users with the function of binding their mobile phone and email, so that users can receive important account security information through their mobile phone or email when needed. When users bind their mobile phone and email address, they need to perform legality verification to ensure that the entered mobile phone number and email address are valid.

5. Function of setting security questions
The mall website can provide the function of setting security questions so that users can reset their passwords by answering the security questions when they forget their passwords. When setting security questions, users should choose questions whose personal information is not easily guessed by others, and should keep the answers to the questions properly.

6. Login restriction function
The mall website can set up the login restriction function to automatically lock the user account when the user fails to log in multiple times in a row. When a user's account is locked, a reminder email should be sent to the user that the account is locked, and the corresponding unlocking method should be provided.

7. Real-name authentication function
The mall website can provide real-name authentication function to verify the user's identity. When performing real-name authentication, users need to enter their ID number and other relevant information, and upload a photo of their ID card for review. When users perform important operations such as shopping, mall websites can give priority to real-name authentication user requests.

8. Security log function
The mall website should record the user's login behavior and other important operation behaviors, and retain corresponding security logs. When a security incident occurs, you can search and analyze it based on the security log so that you can take appropriate security measures in a timely manner.

Summary
Through the above measures, the user account security setting function can be realized using the PHP Developer City. Mall websites should comprehensively consider password security, password retrieval, password modification, binding mobile phone and email, setting security questions, login restrictions, real-name authentication and security logs to provide users with reliable account security.
