1.通过memecache扩展

配置:

session.save_handler = memcache
session.save_path = "tcp://host:port"

phpinfo中变量值:
Registered save handlers files user sqlite memcache

测试

2)test1.php

<?php

session_start();

if (!isset($_SESSION['TEST'])) {   

$_SESSION['TEST'] = time();

}

$_SESSION['TEST3'] = time();
print $_SESSION['TEST'];
print $_SESSION['TEST3'];
print session_id();

输出:

1234506445

1234506445

3bbf03b9cedace4e0164a0c3d56712d1

3)test2.php

取test1.php输出的sessionid来测试

$memcache = memcache_connect('211.162.58.77', 11211);
var_dump($memcache->get('3bbf03b9cedace4e0164a0c3d56712d1'));


输出:

string(37) "TEST|i:1234503252;TEST3|i:1234503398;"

至此,测试成功!

2.通过session_savehandlr人扩展

Some PHP code for memcached session handler. 

<?php 
class SessionHadler 
{ 
     private static $lifetime = 0; 

     public static function open() 
     { 
         self::$lifetime = ini_get('session.gc_maxlifetime'); 
         
         return true; 
     } 
     
     public static function read($id) 
     { 
         return memcached::get("sessions/{$id}"); 
     } 
     
     public static function write($id, $data) 
     { 
         return memcached::set("sessions/{$id}", $data, self::$lifetime); 
     } 
     
     public static function destroy($id) 
     { 
         return memcached::delete("sessions/{$id}"); 
     } 
     
     private function __construct(){} 
     public static function gc(){ return true; } 
     public static function close(){    return true; } 
     public function __destruct() 
     { 
         session_write_close(); 
     } 
 } 
?>
