数组使用foreach变对象了

            $session_list = Db::table('x_session')->get();
            $session_list = $session_list->toArray()
            //$session_list gettype 值为array
            //toArray 只是改变session_list类型吗
            $session_temp = [];
            foreach ($session_list as $key => $value) {
                //$value gettype 值为 object
            }
