Do I have to include header and footer in every controller?

[eluser]Unknown[/eluser]
So, if I have the same header and footer, do I have always to include it like this?

Code:

<?php
class Welcome extends Controller {

    function index() {
        $data['title'] = 'My title';
        // Javascript, CSS, etc...

        $this->load->view('header', $data);

        $data = array();
        // Content view data
        $this->load->view('my_content_view', $data);

        $data = array();
        // Copyright, sitemap, links, etc...
        $this->load->view('footer', $data);
    }
}
?>

?
