Article Introduction：Overview of PHP Fast Cache Introduction and Usage Guide: In today's Internet application development, performance has always been the focus of developers. In high-concurrency scenarios, special attention needs to be paid to data reading and loading efficiency. As a scripting language, PHP has relatively low operating efficiency, so caching plays an extremely important role. This article will introduce the concept of PHP fast caching and how to use caching to improve application performance. What is cache? Cache is a means of saving data by saving some data obtained through calculation or IO operations in order to

Article Introduction：1. Introduction EhCache is a pure Java in-process caching framework, which is fast and capable. It is the default CacheProvider in Hibernate. Ehcache is a widely used open source Java distributed cache. Mainly for general cache, JavaEE and lightweight containers. It features memory and disk storage, cache loaders, cache extensions, cache exception handlers, a gzip cache servlet filter, support for REST and SOAP APIs, and more. Features: Fast and simple. Various caching strategies. There are two levels of caching data: memory and disk, so there is no need to worry about capacity issues. The cached data will be written to the disk during the restart of the virtual machine. It can be inserted through RMI.

Article Introduction：Data caching mechanisms include memory cache, database cache, file cache, distributed cache, local cache, message queue cache, compression cache, LRU, LFU and FIFO, etc. Detailed introduction: 1. Memory cache is one of the most common forms of data caching. It stores data in the computer's RAM for faster access and use. The advantage of memory cache is fast access, but the disadvantage is limited memory resources. , not suitable for storing large amounts of data; 2. Database caching refers to storing data in a database system, improving data through query optimization, indexing and other technologies, etc.

Article Introduction：There are five common types of in-network caching mechanisms: "proxy server cache", "content distribution network cache", "router cache", "DNS cache" and "accelerator cache": 1. Proxy server cache, the proxy server is usually located on the client Between it and the original server, it can cache static content such as Web pages, pictures, videos, etc. that have been visited; 2. Content distribution network caching, which provides a network architecture for fast content delivery by deploying cache nodes located around the world; 3. Router Cache, use cache to store recently passed data packets or routing information, etc.

Article Introduction：Analysis of the principles and advantages of PHP fast caching Caching is one of the important means to improve the performance of Web applications. In PHP development, we can use caching to improve page loading speed and database access efficiency. This article will introduce the principles of PHP fast caching and analyze its advantages. Principle The principle of PHP fast caching is based on storing dynamically generated content in static files, thus avoiding the need to regenerate the content with every request. When the user sends a request, first check whether the cache file exists, and if it exists, directly return the cache content, saving the database

Article Introduction：1. Evolution of large-scale website architecture A. Large-scale website software systems are characterized by high concurrency, large traffic; high availability; massive data; widely distributed users, complex network conditions; poor security environment; rapid changes in requirements, frequent releases; progressive development; B .Evolution and development process of large-scale website architecture 1. Initial stage: one server, LNMP 2. Separation of application services and data services: application server (CPU); database server (fast disk retrieval and data caching); file server (large hard disk); 3 .Use cache to improve website performance: local cache cached on the application server (fast access, limited by application server memory, limited data volume), remote distributed cache (use a cluster to deploy a server with large memory as a dedicated cache server)
