Set the session in PHP to use Memcache to store the method to summarize the _php instance

Memcached provides a custom session processor that can be used to store user session data to the memcached server. A completely separate memcached instance will be used internally, so you can set up a different server pool if needed. The session key is stored under the prefix Memc.sess.key, so if you use the same server pool for the session and the usual cache, be aware of this. Another session and the usual reason for cache separation is that when the usual cache fills the memcached server, it may cause your session to be kicked out of the cache, causing the user to fall out of line.

Session.save_handler string

Set to memcached to turn on the memcached session processor.

Session.save_path string

Defines a comma-delimited Hostname:port-style session cache server pool, for example: "sess1:11211, sess2:11211".

Method I: Global settings in php.ini

Method II: In a directory. htaccess

Method III: Again or in one application

Use multiple memcached servers separated by commas "," and, as described in the memcache::addserver () documentation, can take additional parameters "persistent", "weight", "timeout", "Retry_ Interval "And so on, like this:" Tcp://host1:port1?persistent=1&weight=2,tcp://host2:port2 ".

If the installed pecl is memcached (which relies on the extension of the libmemcached library), the configuration should be

Ini_set ("Session.save_handler", "memcached"); is memcached not memcache ini_set ("Session.save_path", "127.0.0.1:11211"); Don't tcp:[/b]

code example (the one that does not depend on the libmemcached library)

<?php session_start (); if (!isset ($_session[' test ')) {$_session[' test '] = time ();} $_session[' test '] = time (); Print $_session[' TEST ']; Print "

"; Print $_session[' TEST ']; Print "

Use SessionID to go to memcached to check:

<?php $memcache = memcache_connect (' localhost ',); Var_dump ($memcache->get (' Ccedecbceebe ')); $memcache->set (' aaaa ', ' hello everyone '); Var_dump ($memcache->get (' aaaa '));?>

'll see

String (PNS) "test|i:1177556731; test3|i:1177556881; "

This output proves that the session is working properly.

Here are two examples of usage to introduce PHP using memcached to store the session

One

Ini_set ("Session.save_handler", "Memcache"), Ini_set ("Session.save_path", "tcp://127.0.0.1:11211");

Multiple memcached

Ini_set ("Session.save_path", "tcp://127.0.0.1:11211,tcp://127.0.0.1:11211");

Two

Ini_set ("Session.save_handler", "memcached"); Ini_set ("Session.save_path", "...:");

Multiple memcached

Ini_set ("Session.save_path", "127.0.0.1:11211,127.0.0.1:11211");
