In CodeIgniter, you can get session data by using the session library that comes built-in with the framework. Here's a step-by-step guide on how to retrieve session data:

  1. Load the session library in your controller or model:
1
$this->load->library('session');


  1. To retrieve a specific session data, you can use the userdata() method and pass in the key of the data you want to retrieve:
1
$data = $this->session->userdata('key');


  1. If you want to retrieve all the session data, you can use the all_userdata() method:
1
$data = $this->session->all_userdata();


  1. You can also use the flashdata() method to retrieve flash data, which is data that is only available for the next request:
1
$data = $this->session->flashdata('key');


  1. Finally, you can use the unset_userdata() method to remove a specific session data:
1
$this->session->unset_userdata('key');


That's it! You can now retrieve session data using the session library in CodeIgniter.
