How to include header footer in CodeIgniter

Include header and footer is very easy in CodeIgniter.First of all create a common file in view folder.In this example i create a file name as start.php .


	include_once "header.php";
	include_once $pageName.'.php';
	include_once "footer.php";


<!DOCTYPE html>
<title>Hello World !</title>

<h1>Main Content</h1>





defined('BASEPATH') OR exit('No direct script access allowed');

class Welcome extends CI_Controller {

	 * Index Page for this controller.
	 * Maps to the following URL
	 * 		http://example.com/index.php/welcome
	 *	- or -
	 * 		http://example.com/index.php/welcome/index
	 *	- or -
	 * Since this controller is set as the default controller in
	 * config/routes.php, it's displayed at http://example.com/
	 * So any other public methods not prefixed with an underscore will
	 * map to /index.php/welcome/<method_name>
	 * @see https://codeigniter.com/user_guide/general/urls.html
	public function index()
		$data['pageName']= 'home';
