如何仅更新部分会话值CODEIGNITER

Question

所以我有一个会话变量

  $info = $this->session->userdata('userInfo');

它有一个数据

 [user] => stdClass Object
    (
        [student_id] => 201410679
        [firstname] => NEHEMIAH
        [midname] => ONGTANGCO
        [lastname] => BALUYUT
        [username] => nobaluyut
        [password] => nobaluyut
        [email] => [email protected]
        [student_department] => CE
        [image_path] => assets/img/profiles/profile.jpg
        [student_is_blocked] => 1
        [offering_id] => 1
    )

[logged_in] => 1
[identifier] => student
[active_enrollment] => 1

如何在不覆盖整个会话变量的情况下更新[user] [student_is_blocked]？

Answer 1

如果'userInfo'是会话变量并且其中包含数组和变量。然后

$info = $this->session->userdata('userInfo');
$info['user']->student_is_blocked= "Any Value";
$this->session->set_userdata('userInfo', $info);
