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:

To get session in CodeIgniter, you can use the session() function provided by the framework.


Here is an example of how to use it:

  1. First, make sure the session library is loaded in your controller or autoloaded in config/autoload.php:
1
$this->load->library('session');


  1. Now, you can use the session() function to get and set session data. For example, to get the value of a session variable named 'username', you can do:
1
$username = $this->session->userdata('username');


  1. Similarly, you can set a session variable like this:
1
$this->session->set_userdata('username', 'john_doe');


You can also pass an associative array to set multiple session variables at once:

1
2
3
4
5
6
$data = array(
    'username' => 'john_doe',
    'email' => '[email protected]'
);

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


Note that the session data will be available throughout the current session until it is destroyed or expired.
