How to properly pass variable to controller via routes.php in Laravel?

Question

Laravel

Here is the code that, according to the idea, should pass $id to the controller.

Route::get('categories/id/{$id}', '[email protected]');

Here is the method in the controller:

class CategoriesController extends BaseController {

  public function testListByID($id)
  {
echo $id;
  }
}

I go to:
localhost/lvtest/public/categories/id/2
Basically I should get a value of 2 here, but instead this is:

What am I doing wrong?

Answer 1

Route::get('categories/id/{$id}', '[email protected] postListByID ');
and in the controller...
public function testListByID ($id)

Answer 2

Not so - vtest/public your url should be something like
localhost:8000/categories/id/2
if without using an internal server, then specify a virtualhost.
