You can access the session using a session id in CodeIgniter by using the following steps:

1. Make sure you have session library loaded in your CodeIgniter controller.
2. Retrieve the session id from the user. This could be passed as a parameter in the URL, or sent along with a form submission.
3. Use the session library's sess_read method to pull the session data using the session id. Here is an example code snippet:

1
2
3
4
5
6

$session_id = 'your_session_id_here'; // Retrieve the session id from the user

$this->load->library('session');
$session_data = $this->session->sess_read($session_id);

// Now you can access the session data using the $session_data variable

1. You can now access the session data stored in $session_data variable.

Remember, it is important to handle session id securely and validate it before using it to prevent any security vulnerabilities.
