Userguide CI 3.0 error

There is also confusing PHP declaration in Static pages:

PHP Code:

<?php // confusing declaration, it should not be here
public function view($page = 'home')
{

    if ( ! file_exists(APPPATH.'/views/pages/'.$page.'.php'))
    {
        // Whoops, we don't have a page for that!
        show_404();
    }

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

    $this->load->view('templates/header', $data);
    $this->load->view('pages/'.$page, $data);
    $this->load->view('templates/footer', $data);

}
