in php.ini

Copy code The code is as follows:

session.save_hander = memcache;
session.save_path = "tcp:// host:port number";//For example: session.save_path = "tcp://127.0.0.1:11211";

ini_set( 'session.save_path', 'tcp://127.0.0.1:11211');

b. Normal access to the session value is OK.

Comparison between Memcache and Session
The main purpose of memcache is to relieve database pressure and speed up, so it is a kind of stateless data (stateless data: the current data is not bound to a certain user, such as: Lee Richard can take out the stored data, as long as he knows the corresponding key value)
Session data is bound to the user, so it is a stateful data.

Security of Memcache
Put memcache into the intranet and use a firewall to block external access

Suitable for data stored in Memcached
Data that changes frequently, is unstable, does not need to be stored in real time, and has low security
