Use memcache to save session

By default, the session is saved in the form of a file on the server side. When we encounter large traffic and high concurrency, we will cluster the web server. Then session sharing between different servers will become a problem.

Using memcache to save the session can improve the access speed of the session. At the same time, the problem of session sharing can be solved.

It is very easy to use memcache to save session in php language.

Use php code to complete the use of memcache to save the session

ini_set("session.save_handler", "memcache");
ini_set("session.save_path", "tcp://127.0.0.1:11211");
session_start();
