ci3如何在视图中获取session保存的变量值？

控制器中

public function index()
{
       $this->load->library('session');
       $name = $_SESSION;


       $base_url = $this->config->item('base_url');

       $this->load->view('indexx/index',array('base_url'=>$base_url,'name'=>$name));
}

视图中

<h2><span class="profile"><span><?php echo $name['admin']; ?></span></span></h2>
