How to use URL to define response type

With codeigniter, you'd probably do something like /class/method/type.
Your function would look like

Code:

public function method($type='html'){
    switch($type){
        case 'json':
        //code here
        break;
        ...
    }
}

Maybe in your routes you could define a route to move the type to the front

$routes['json/(:any)'] = '$1/json';
