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');

Simple :
First, load this library
$this->load->library('session');
Then, to add some informations in session :
$newdata = array(
'username' => 'johndoe',
'email' => '[email protected]',
'logged_in' => TRUE
);
$this->session->set_userdata($newdata);
Next, if you want to get values :
$session_id = $this->session->userdata('session_id');
And to remove :
$this->session->unset_userdata('some_name');

I consider storing my session data in a controller. So this is how you should go about storing and retrieving session data
- Use autoload in your config.php files. It saves you time and load time
autoload['libraries'] = ('session);
- In your controller.php create an array to store your session data.
$new_data = array( 'username' => 'martin',
'email' => '[email protected]',
'user_logged => TRUE );
$this->session->set_userdata($new_data);
- Then this is how to call your session data(create a variable and assign it the value of one of the session data you need):
$username = $this->session->userdata('username');

Codeigniter
set in session
$newdata = array(
'username' => 'johndoe',
'email' => '[email protected]',
'logged_in' => TRUE
);
$this->session->set_userdata($newdata);
retrieve from session
$this->session->userdata('username');
