在PHP中的数据库中设置会话

您将需要创建一个像这样的对象：

class SessionHandler {     private static $lifetime = 0;    private function __construct() //object constructor    {        session_set_save_handler(array($this,'open'),array($this,'close'),array($this,'read'),array($this,'write'),array($this,'destroy'),array($this,'gc')       );    }   public function start($session_name = null)   {       session_start($session_name); //Start it here   }    public static function open()    {        //Connect to mysql, if already connected, check the connection state here.        return true;    }    public static function read($id)    {        //Get data from DB with id = $id;    }    public static function write($id, $data)    {        //insert data to DB, take note of serialize    }    public static function destroy($id)    {       //MySql delete sessions where ID = $id    }    public static function gc()    {        return true;    }    public static function close()    {        return true;    }    public function __destruct()    {        session_write_close();    }}

然后，在session_start之前，初始化此类！

include 'classes/sessionHandlerDB.php';$session = new SessionHandler();$session->start('userbase');$_SESSION['name'] = 'Robert Pitt'; //This is sent to SessionHandler::write('my_id','Robert Pitt')echo $_SESSION['name']; //This calls SessionHandler::read($id)//$id is Unique Identifier for that
