我从以下位置获取会话：
echo '<pre>';
print_r($this->session->all_userdata());
exit;
结果是：
Array
(
[session_id] => 47fa796fbc6c5146a5ba0b1e596f4354
[ip_address] => ::1
[user_agent] => Mozilla/5.0 (Windows NT 6.1; rv:47.0) Gecko/20100101 Firefox/47.0
[last_activity] => 1468617532
[user_data] =>
[session_data] => Array

)
[default] => 0
）
我只想要[default] => english的值，而不是任何其他数组对象。我还想将其存储在任何变量中，但我无法弄清楚如何在 CI 中做到这一点。
使用这个
//you can access any session data by session name using this // default is a session name
$session_default = $this->session->userdata('default');
echo $session_default ; // english
你也可以使用这个
$data = $this->session->all_userdata();
$session_default = $data['session_data']['default']);
echo $session_default ;
// english
