CodeIgniter time ago format achieved

http://tutorialsbay.com/codeigniter-time-ago/

I wrote one custom function to achieve this

function display_time($timestamp) {
  $date_array = explode(',', timespan($timestamp, time()));
  $date = $date_array[0] . ' AGO, ';
  return($date);
}

Facebook PHP SDK logout : resolved

Facebook sdk is creating one cookie in browser.
Which has to be cleared on logout.
Here is my Codeigniter code to do that.

Logout URL
$this->facebook->getLogoutUrl(array('next' => site_url('user/logout'));


Logout Function

 public function logout() {
    setcookie('PHPSESSID', '', time()-3600, "/");
    $this->session->sess_destroy();
    redirect('/user', 'refresh');
  }

      show_404();
    }

    $data['title'] = ucfirst($page); // Capitalize the first letter

    $data['header'] = $this->load->view('templates/header', $data, true);
    $data['body'] = $this->load->view('pages/' . $page, $data, true);
    $data['footer'] = $this->load->view('templates/footer', $data, true);

    $this->load->view('templates/page', $data);
  }
