把session存到memcache里

设置
[php]
ini_set("session.save_handler", "memcache");
ini_set("session.save_path", "tcp://127.0.0.1:12000"); 

session_start();
$_SESSION["xxx"] = "test";

echo session_id();
[/php]

验证

$mem = new Memcache;
$mem->connect('127.0.0.1', 12000);
$xxx = $mem->get("xxxxxxxoooooooooo");  //上面的session_id()
var_dump($xxx);
