这个是一个php对session的再次包装的类,实现的常用的session操作,包含读取,写入,销毁等等
class Session { function Session() { session_start(); } function set($name, $value) { $_SESSION[$name] = $value; } function get($name) { if(isset($_SESSION[$name])) return $_SESSION[$name]; else return false; } function del($name) { unset($_SESSION[$name]); } function destroy() { $_SESSION = array(); session_destroy(); } function save_prefs() { global $db, $auth; $prefs = serialize($this->prefs); $db->query("UPDATE condra_users SET prefs = '$prefs' WHERE id = '{$auth->id}'"); } }
