Complete parsing of basic Memcache functions in PHP and complete parsing of memcache

What is Memcache?

Memcache is a danga.com project that was first used for LiveJournal. Many people around the world use this cache project to build their own websites with high load to share the pressure on databases.

It can cope with any number of connections and use non-blocking network I/O. Because its working mechanism is to open up a space in the memory, and then create a HashTable, Memcached self-manages these HashTable.

Official website of Memcache: http://www.danga.com/memcached. For more detailed information, see here :)
Why are there two Memcache and memcached names?

In fact, Memcache is the name of this project, and memcached is the name of the main program file on its server ~~~~. One is the project name, the other is the main program file name, and many people on the Internet do not understand it, so it is mixed.

The Memcache module provides convenient process-oriented and object-oriented interfaces for Memcached. Memcached is a resident process cache product generated to reduce the workload of Dynamic web applications loading data from databases. The Memcache module also provides a session processor (memcache ). The following PHP programmer Lei xuesong will explain in detail how PHP operates the basic Memcache functions.
