Set the session to use memcache for storage

Method I: global settings in php. ini
Session. save_handler = memcache
Session. save_path = "tcp: // fig: 11211"


Method II:. htaccess under a directory
Php_value session. save_handler "memcache"
Php_value session. save_path "tcp: // fig: 11211"


Method III: or in an application

1 ini_set("session.save_handler", "memcache"); 2 ini_set("session.save_path", "tcp://127.0.0.1:11211");



Multiple memcached servers are separated by commas (,), which are the same as those described in the Memcache: addServer () document, you can include additional parameters such as "persistent", "weight", "timeout", and "retry_interval". for example, "tcp: // host1: port1? Persistent = 1 & weight = 2, tcp: // host2: port2 ".

If the installed PECL is memcached (the extension dependent on the libmemcached Library), the configuration should be
Add Php code to favorites
Ini_set ("session. save_handler", "memcached"); // it indicates that memcached is not memcache.
Ini_set ("session. save_path", "127.0.0.1: 11211"); // do not use tcp: [/B]


Code example (not dependent on the libmemcached Library)

 1 
 
"; 11 print $_SESSION['TEST3']; 12 print "

"; 13 print session_id(); 14 ?>

Use sessionid to query in memcached:

?

1

2

3

4

5

6

$memcache = memcache_connect('localhost', 11211);

var_dump($memcache->get('19216821213c65cedec65b0883238c278eeb573e077'));

$memcache->set('aaaa', 'hello everyone');

var_dump($memcache->get('aaaa'));

?>

You will see
String (37) "TEST | I: 1177556731; TEST3 | I: 1177556881 ;"
This output proves that the session works normally.
