How to add user operation records to PHP forms to improve security

With the rapid development of Internet technology, more and more websites use PHP forms to collect user information. However, the risks that come with it are getting higher and higher, because hackers may use the form to capture users' private information or conduct malicious attacks. In order to prevent these risks, we need to add user operation records to PHP forms to improve security.

1. What is user operation record

User operation record records all operations of each user when using the system, including logging in, registering, filling out forms, submitting forms, etc. These records can be used to track user behavior. If abnormal operations occur, corresponding security measures can be detected in time and taken.

2. How to add user operation records to PHP forms

1. Use session

session is a mechanism in PHP used to track users operations between pages. You can use session to record the user's login status, user's browsing history, etc. When the form is submitted, the session data is saved to the database, and then when a query is needed, the data is read from the database for analysis.

2. Use of cookies

Cookies are also a technology used to save user data. The difference from session is that cookie data is stored on the client side, while session data is stored on the server side. Cookies can be used to record the user's operation path, and these data can be read from the cookie for analysis when needed.

3. Create a log table in the database

When the form is submitted, save the form data to the log table. When you need to query user operation records, you can obtain relevant data by querying the log table. This method can improve efficiency, but you need to pay attention to the consumption of database write operations.

3. How to use user operation records to improve security

1. Security audit

By analyzing user operation records, some abnormal operations can be discovered. For example, submitting a form without logging in, or submitting the same form multiple times in a short period of time, etc. These operations are likely to be malicious attacks on the system by hackers. By discovering and blocking these operations in time, the security of the system can be greatly improved.

2. System monitoring

Monitoring user operation records can help administrators discover system bottlenecks and performance problems in a timely manner. By analyzing operational data, you can identify stages or bottlenecks where system processing speed is slower, and then optimize the system.

3. Data Analysis

Analyzing user operation records can help administrators better understand user needs and behaviors. By collecting user feedback and suggestions, system design and functions can be optimized, user experience improved, and user loyalty enhanced.

To sum up, adding user operation records can improve the security, performance and user experience of the system. It should be noted that user operation records need to protect user privacy, and sensitive data cannot be recorded in the record table. At the same time, administrators need to clean log data regularly to avoid excessive data burdening the system.
