Answer 1

You don't have to set the session the PHP way.

CodeIgnter has its on Session Class

Load the session library:

$this->load->library('session');

To set session data:

$this->session->set_userdata('some_name', 'some_value');

To retrieve session data:

$this->session->userdata('some_name');

To remove session data:

$this->session->unset_userdata('some_name');
