How to Get Session Data in CodeIgniter
To get session data on controllers and views in CodeIgniter is a simple process. By following these steps, you can store user-specific data and retrieve it whenever needed:

Step 1: Start a Session
Before getting session data, it is important to start a session in CodeIgniter. This can be done by calling the session library in your controller constructor or autoload.php file.
$this->load->library('session');
Step 2: Set Session Data
To set session data, you can use the set_userdata() method of the session library. For example, let’s say you want to set the user’s name in the session data.
$this->session->set_userdata('username', 'John');
Step 3: Get Session Data in Controller
To get session data in the controller, you can use the userdata() method of the session library. For example, to get the user’s name from the session data:
$username = $this->session->userdata('username');
Step 4: Pass Session Data to Views
To pass session data to views, you can use the second parameter of the $this->load->view() method. For example, let’s say you want to pass the user’s name to the header view:
$data['username'] = $this->session->userdata('username');
$this->load->view('header', $data);
Step 5: Display Session Data in Views
To display session data in views, you can simply echo the variable that was passed to the view. For example, in the header view:
Welcome, <?php echo $username; ?>
