There is no ready-made method
If you want to achieve the function you mentioned
Generally speaking, you should increase or decrease the value of the table through insert or remove in the normal way
And then add additional Perform a monitoring on the table and when the specified time is reached, remove the relevant values
Redis will store data in memory and will be lost when power is turned off. Pay attention to this and make it persistent if necessary. The persistence method is difficult to explain in one sentence, you can refer to online articles.
php’s redis extension is called php-redis. There is a Chinese manual for php-redis on the Internet. Here is an example:
connect('127.0.0.1', 6379); / / 6379 is the default port $result = $redis->set('9639002718',"comment"); // Set the key value echo $result = $redis->get('9639002718'); // Get the key value $all = $redis->getMultiple(array('9639002718', '9639002718')); // Get multiple key values at the same time // There is no method to get all key values. I'm not sure if the following sentence can be used, you can give it a try. $all = $redis->getMultiple(array('*'));
Hope to adopt it, thank you for your support!

In PHP, you can use session_status() or session_id() to check whether the session has started. 1) Use the session_status() function. If PHP_SESSION_ACTIVE is returned, the session has been started. 2) Use the session_id() function, if a non-empty string is returned, the session has been started. Both methods can effectively check the session state, and choosing which method to use depends on the PHP version and personal preferences.

Managing concurrent session access in PHP can be done by the following methods: 1. Use the database to store session data, 2. Use Redis or Memcached, 3. Implement a session locking strategy. These methods help ensure data consistency and improve concurrency performance.

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.
