Working with sessions in CodeIgniter 4: This tutorial could show how to use the session library in CodeIgniter 4 to store and retrieve data across multiple pages and requests.

To use the session library, you will need to load it in your controller using the library function:

Once the session library is loaded, you can use its functions to store and retrieve data in the session.

To store data in the session, you can use the set function:

$this->session->set('key', 'value');

To retrieve data from the session, you can use the get function:

$value = $this->session->get('key');

You can also use the set_userdata and userdata functions to store and retrieve arrays of data in the session:

$data = [
  'username' => 'john.doe',
  'email' => 'john.doe@example.com',
];

$this->session->set_userdata($data);

$userdata = $this->session->userdata();

To remove data from the session, you can use the unset_userdata function:

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

I hope this helps you get started with working with sessions in CodeIgniter 4. Let me know if you have any questions or if you’d like more information on a specific topic.
