PHP caching

Several methods of PHP cache processing:
1. To determine where the bottleneck is, the problem often occurs in the database
2. memcached or redis
3. Memcached is a high-performance distributed memory object caching system used in dynamic web applications to reduce database load. It improves the speed of dynamic, database-driven websites by caching data and objects in memory to reduce the number of database reads. Memcached is based on a hashmap that stores key/value pairs. Its daemon is written in C, but the client can be written in any language and communicates with the daemon through the memcached protocol.
4. You can use nginx on the server side
Nginx is a lightweight web server/reverse proxy server and email (IMAP/POP3) proxy server, and is released under a BSD-like protocol. It was developed by Russian programmer Igor Sysoev and is used by Rambler (Russian: Рамблер), a large Russian portal website and search engine. Its characteristics are that it occupies less memory and has strong concurrency capabilities. In fact, nginx’s concurrency capabilities do perform better among web servers of the same type. Users of nginx websites in mainland China include: Sina, NetEase, Tencent, etc.

The above has introduced PHP cache processing, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.
