提问by manuthalasseril
I would set a session value in codeigniter
我会在 codeigniter 中设置一个会话值
$sess_array = array(
'id' => $row->Login_Id,
'username' => $row->Login_Name,
'postid'=> $row->Fk_Post_Id,
);
$CI->session->set_userdata('logged_in', $sess_array);
Then how to retrieve a particular (say - id) session value . I tried these

为此使用数组语法。喜欢，

Session write process. session content could be dynamic value
$logged_in = [
'id'=> 1,
'name'=> 'test'
];
Particular Session retrieve process.
$this->session->userdata['logged_in']['id'];

$pdata = array(
'id' => $row->Login_Id,
'username' => $row->Login_Name,
); // pass ur data in the array
$this->session->set_userdata('session_data', $pdata); //Sets the session
$pdata = $this->session->userdata('session_data'); //Retrive ur session
$pdata['id'] will give u the corresponding id

In newer version, you can simply use
在较新的版本中，您可以简单地使用
$this->session->username
$this->session->id
$this->session->postid
