In CodeIgniter, you can restore a session by session ID using the session_id() function. Here is an example of how you can do this in your controller:

public function restore_session($session_id) {
    $this->load->library('session');

    // Set the session id
    $this->session->sess_regenerate(TRUE);
    $this->session->set_userdata('session_id', $session_id);

    // Restore the session data
    $this->session->sess_destroy();
    $this->session->sess_create();

    // You can now access session data as usual
    $data = $this->session->userdata('some_data');

    // Redirect to a page or do some other action
    redirect('dashboard');
}


In this code snippet, we first load the session library using $this->load->library('session'). Then, we set the session ID using $this->session->set_userdata('session_id', $session_id).


Next, we regenerate the session data by calling $this->session->sess_destroy() and $this->session->sess_create(). This will destroy the current session data and recreate it using the new session ID.


After that, you can access session data as usual using $this->session->userdata('some_data'). Finally, you can redirect to a page or perform any other action needed.
