[Turn]php use Memcache to store session

Transferred from: http://koda.iteye.com/blog/466667

memcache and PHP memcach extension installation see http://koda.iteye.com/blog/665761

set session with Memcache to store  

method I: Global settings in php.ini  

PHP.ini Code

1. Session.save_handler = Memcache
2. Session.save_path = "tcp://127.0.0.1:11211"

Method II: In a directory. htaccess  

PHP.ini Code

1. Php_value session.save_handler "Memcache"
2. Php_value session.save_path "tcp://127.0.0.1:11211"

Method III: Again or in one application  

PHP code

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

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

PHP code

1. Ini_set ("Session.save_handler", "memcached"); //Is memcached not memcache
2. Ini_set ("Session.save_path", "127.0.0.1:11211"); //Do not tcp:[/b]

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

PHP code

2. <?php
4. Session_Start ();
6. if (!isset ($_session[' TEST '])) {
8. $_session [' TEST '] = time ();
10. }
14. $_session [' TEST3 '] = time ();
18. Print $_session[' TEST '];
20. Print "<br><br>";
22. Print $_session[' TEST3 '];
24. Print "<br><br>";
26. Print session_id ();
28. ?>

use SessionID to go to memcached to check:  

PHP code

1. <?php
2. $memcache = memcache_connect (' localhost ', 11211);
3. Var_dump ($memcache->get (' 19216821213c65cedec65b0883238c278eeb573e077 '));
4. $memcache->set (' aaaa ', ' Hello everyone ');
5. Var_dump ($memcache->get (' aaaa '));
6. ?>

'll see
String (PNS) "test|i:1177556731; test3|i:1177556881; "
This output proves that the session is working properly.
