Codeigniter convert excel file to pdf

Question

How can I convert excel to pdf?

I want to put 5 excel files and after I click upload convert them to 1 pdf.

My code: 

    /**
 * Example: DOMPDF 
 *
 * Documentation: 
 * http://code.google.com/p/dompdf/wiki/Usage
 *
 */
public function index() {   
    // Load all views as normal
    $this->load->view('test');
    // Get output html
    $html = $this->output->get_output();

    // Load library
    $this->load->library('dompdf_gen');

    // Convert to PDF
    $this->dompdf->load_html($html);
    $this->dompdf->render();
    $this->dompdf->stream("welcome.pdf");

}

The library:

class Dompdf_gen {

public function __construct() {

    require_once APPPATH.'third_party/dompdf/dompdf_config.inc.php';

    $pdf = new DOMPDF();

    $CI =& get_instance();
    $CI->dompdf = $pdf;

}

}

This is a basic php script for converting Excel to PDF; you may use it and convert it to a subclass of CodeIgniter as well. To make PDF as you choose, you must first dump all Excel data into a PHP array or var.
