Code:

function checker()
    {
        $is_logged_in = $this->session->userdata('is_logged_in');
        if(!isset($is_logged_in) || $is_logged_in != true)
        {
            return true;
        }
        
    }

Code:

$this->session->userdata('is_logged_in')

...according to the manual this call will either return the value you set in it (boolean perhaps?) or FALSE if that session key (is_logged_in) is not found.

isset() simply checks to see if the variable is set. Since you set it before your if statement,

Code:

!isset($is_logged_in)

will never be true because

Code:

isset($is_logged_in)

is always true.

In fact, as long as you are setting boolean values to the session item, you can probably make this function a one-liner:

Code:

function checker(){
     return $this->session->userdata('is_logged_in');
}
