To create and use 2 variables in a session in CodeIgniter, you can follow these steps:

1. Load the session library in your controller or autoload it in config/autoload.php:

1

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

1. Set the session variables using the set_userdata() method:

1
2

$this->session->set_userdata('variable1', 'value1');
$this->session->set_userdata('variable2', 'value2');

1. Retrieve the session variables using the userdata() method:

1
2

$variable1 = $this->session->userdata('variable1');
$variable2 = $this->session->userdata('variable2');

1. Unset or destroy the session variables when they are no longer needed:

1
2

$this->session->unset_userdata('variable1');
$this->session->unset_userdata('variable2');

or

1

$this->session->sess_destroy();

Remember to also configure the session settings in config.php to make sure the session data is stored and managed properly.
