Redis dynamic and static separation in PHP applications

With the development of the Internet, more and more website applications need to quickly respond to read and write operations of massive data. At this time, NoSQL databases have gradually become the new favorite in the big data era. As a member of the NoSQL database, Redis is selected and used by many website applications because of its high speed, high performance, high scalability and other characteristics.

Redis is becoming more and more widely used in PHP applications, but it is a bit simple and crude to just use Redis as a cache for PHP applications. Redis is essentially a memory-based high-performance database. In PHP applications, we can use Redis as a database to store some commonly used system configuration information, calculation results, etc., or as a cache to cache some hot data to improve system performance.

But in actual applications, many application engineers have not fully utilized the advantages of Redis. When using Redis in PHP applications, we can make full use of the advantages of Redis and improve the performance and stability of the system by separating Redis dynamically and statically.

Dynamic and static separation is a technology that allocates dynamic requests and static requests in the system to different servers for processing. In the application of Redis, we can use it in PHP applications to improve the speed and stability of the system by storing dynamic data in MySQL and static data in Redis.

The following are the specific implementation steps:

1. First, distinguish whether the page is a static request or a dynamic request.

2. Store the data in dynamic requests in MySQL, and cache the data in static requests in Redis.

3. When accessing a page, the system first determines whether the request is a static request. If so, it obtains the corresponding data directly from Redis. If not, it obtains the corresponding data from MySQL.

By separating dynamic data and static data, most access requests for static resources can be transferred from the Web server to the CDN and Redis cache server, thereby reducing the pressure on the Web server and improving the performance of the Web server. , to ensure the stability of the system.

In short, the dynamic and static separation of Redis in PHP applications can make full use of Redis's high speed, high performance, high scalability and other advantages to improve the speed and stability of the system, but the specific implementation needs to be based on the actual situation. We will carry out detailed planning and operations for the situation and hope it will be helpful to everyone.
