        $this->load->view('index');
        $this->load->database();
        $this->load->library('session');
        $this->load->helper(array('form','url'));
        $email    =$this->input->post("email");
        $password  =$this->input->post("password");
        $stmt = $this->db->query("select * from tbl_employees where email='".$email."' and password='".$password."'"); 
        $rowcount = $stmt->num_rows();
        if($rowcount==1) {
        foreach ($stmt->result() as $row)
        {
           $_SESSION['employee_id']=$row->employee_id;
           $_SESSION['first_name']=$row->first_name; 
           $_SESSION['last_name']=$row->last_name;
           print_r($_SESSION); 
           $this->session->sess_destroy();
           redirect('Dashboard/dashboard_index');
           $this->session->sess_destroy();
        }

$this->session->sess_destroy(); or session_destroy(); for CI3 http://www.codeigniter.com/user_guide/libraries/sessions.html#destroying-a-session — José Trindade, Sep 10 '15 at 17:43
What is the issue? You are destroying user session by `$this->session->sess_destroy();` so whats problem in it — Keval Rathi, Sep 11 '15 at 05:32
Why do you say it is *not* destroying the session? What happens instead? — wallyk, Sep 11 '15 at 07:34

Read this: Session Class

Note: The Session class does not utilize native PHP sessions. It generates its own session data, offering more flexibility for developers.

This is a wrong use codeigniter:

$_SESSION['employee_id']=$row->employee_id;

Try this:

$this->session->set_userdata('employee_id', $row->employee_id);
