How to retrieve a particular session value in codeigniter?

codeigniter, php

Solution

Use the array syntax for this. Like,

$this->session->userdata['logged_in']['id'];

Problem

I would set a session value in codeigniter ``` $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 ``` $createdby=$this->session->userdata('id'); $createdby=$this->session->userdata($logged_in['id']); ``` but fails.
