CodeIgniter returning different request format / content type html|json|xml etc

What is a simple way in CodeIgniter that I can return a specific content type for request URL extension? For example I want to return json if the url is http://example.com/phone/digits/1.json, html if the URL ends in /1 or /1.html, and XML if the URL ends in /1.xml. This will load a view in the format specified. So in the above example (phone/digits/1.json) would return the json version of the digits method. Here is what I've got so far that is NOT correctly working but gives an idea of what I'm going for. It's currently generating a 404 if no arguments are passed (/phone/digits.json)... Any suggestions would be appreciated.

class Phone extends CI_Controller {
    public $layout = FALSE;

    public function __construct()
    {
        if (preg_match('/\.(html|json)$/', $ci->uri->uri_string(), $matches))
        {
            $this->format = ('html' == $matches[1] || !isset($matches[1])) ? '' : '.json.php';  
        }
    }

    public function digits()
    {
      $this->load->view('phone/digits' . $this->format);
    }

Updated for clarity,

  • Parse the url
  • grab the extension
  • use a switch condtional and set relevant output

-

switch( $extension ){
    case 'json':
          $this->output
               ->set_content_type('application/json')
               ->set_output(json_encode(array('foo' => 'bar')));
    break;
    case 'xml':
          $this->output
               ->set_content_type('application/xml')
               ->set_output(file_get_contents(some_xml_file.xml));
    break;
    // etc etc
}

I didint understand your question well, asuming you want to simplify your url

its solution for this url : http://domain.com/phone/digits.json (xml or html also) But with few modification , it can be useful also with http://domain.com/phone/digits/n.json (n - id number)

in config/routes.php

$route['phone/digits.(json|html|xml|php)'] = 'Phone/digits/$1';
$route['phone/digits'] = 'Phone/digits';

Controller

class Phone extends CI_Controller {
public $layout = FALSE;

public function __construct()
{
  //hmm
}

public function digits($format = '')
{
   if($format == '') {
     //default view or something else
   }
   else {
      $this->load->view('phone/digits' . $format);
   }
}
