Memcache.hash_strategy = "consistent" / / sets the hash algorithm for memcache
Session.save_path = "tcp://127.0.0.100:11211" / / sets the location where session is stored, and multiple memcache are separated by commas, for example: tcp://127.0.0.1:11211,tcp://127.0.0.1:12000
2. Configure using the .htaccess file in the directory
The copy code is as follows:
Php_value session.save_handler "memcache"
Php_value session.save_path "tcp://127.0.0.1:11211"

Ini_set ("session.save_handler", "memcache")
Ini_set ("session.save_path", "tcp://127.0.0.100:11211")

/ / Test whether the session read is normal
Session_start ()
$_ SESSION ['username'] = "jb51.net"
Echo session_id ()
/ / read session from Memcache
M = new Memcache ()
M-> connect ('localhost', 11211)

/ / $mem- > addServer ("127.0.0.1", 11211) or die ("Can't add Memcache server 127.0.0.1 or die")
/ / obtain data according to session_id
/ / this machine
/ / $session = $m-> get (session_id ()); / / session_id:d527b6f983bd5e941f9fff318a31206b
