How to get session in Codeigniter?

@darrion.kuhn 

In Codeigniter, you can use the built-in session library to store and retrieve data in a session.

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

1

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

Once the session library is loaded, you can use the following methods to store and retrieve data in a session:

• To store data in a session:

1

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

• To retrieve data from a session:

1

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

• To remove data from a session:

1

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

You can also use the $this->session->all_userdata() method to retrieve an array of all the data stored in the session.

For more information on using sessions in Codeigniter, you can refer to the official documentation at the following link:
