PHP actively disconnects from the browser I once compiled an article "In-depth analysis of set_time_limit(), connection_status() and ignore_user_abort() in PHP connection processing", which explains the processing of server PHP scripts when the browser client is disconnected. This article will explain how the server PHP script actively disconnects from the browser. The main method is to use Content-Length and Connection in the http protocol header. The role of Content-Length: After the browser receives the message entity with the specified Content-Length size, it will disconnect from the server. The role of Connection: After the browser receives the Close or Keep-Alive of the Connection, it decides whether to close the connection or continue to use the current connection for the next request. /*** Automatically disconnect from the browser * jiaofuyou */

##8.The background PHP script determines whether the client is interrupted. (Whether the data is actually sent to the front end) Introduction: Search this question. I don’t know how many answers there are, but many of the answers are inaccurate. I will test and summarize. First, everyone agrees that connection_status() or connection_aborted() must be judged, but this The two states can only be obtained after sending data to the front end, that is, it cannot be obtained passively, but can only be obtained actively. Therefore, it is judged that the client is

To protect the application from session-related XSS attacks, the following measures are required: 1. Set the HttpOnly and Secure flags to protect the session cookies. 2. Export codes for all user inputs. 3. Implement content security policy (CSP) to limit script sources. Through these policies, session-related XSS attacks can be effectively protected and user data can be ensured.

Methods to optimize PHP session performance include: 1. Delay session start, 2. Use database to store sessions, 3. Compress session data, 4. Manage session life cycle, and 5. Implement session sharing. These strategies can significantly improve the efficiency of applications in high concurrency environments.

In PHP, you can use the session_name() function to configure the session name. The specific steps are as follows: 1. Use the session_name() function to set the session name, such as session_name("my_session"). 2. After setting the session name, call session_start() to start the session. Configuring session names can avoid session data conflicts between multiple applications and enhance security, but pay attention to the uniqueness, security, length and setting timing of session names.

The session ID should be regenerated regularly at login, before sensitive operations, and every 30 minutes. 1. Regenerate the session ID when logging in to prevent session fixed attacks. 2. Regenerate before sensitive operations to improve safety. 3. Regular regeneration reduces long-term utilization risks, but the user experience needs to be weighed.

Setting session cookie parameters in PHP can be achieved through the session_set_cookie_params() function. 1) Use this function to set parameters, such as expiration time, path, domain name, security flag, etc.; 2) Call session_start() to make the parameters take effect; 3) Dynamically adjust parameters according to needs, such as user login status; 4) Pay attention to setting secure and httponly flags to improve security.

The main purpose of using sessions in PHP is to maintain the status of the user between different pages. 1) The session is started through the session_start() function, creating a unique session ID and storing it in the user cookie. 2) Session data is saved on the server, allowing data to be passed between different requests, such as login status and shopping cart content.

How to share a session between subdomains? Implemented by setting session cookies for common domain names. 1. Set the domain of the session cookie to .example.com on the server side. 2. Choose the appropriate session storage method, such as memory, database or distributed cache. 3. Pass the session ID through cookies, and the server retrieves and updates the session data based on the ID.
