| Routing an unknown number of sub-levels
|--------------------------------------------------------------------------
|
| This is how you can route an unknown number of sub-levels and pass them
| to the same controller. For example, the following URLs will go through
| the same route:
|
| app.dev/
| app.dev/never
| app.dev/never/gonna
| app.dev/never/gonna/give
| app.dev/never/gonna/give/you
| app.dev/never/gonna/give/you/up

Route::get('/{sublevels?}', function($sublevels = null) {

    if (!empty($sublevels)) {
        $sublevels = explode('/', $sublevels);
    }
    
    dd($sublevels);
    
})->where('sublevels', '.*');
