[quote author="smithme08" date="1327362446"]$data["some_value"] is declared in the controller, but is accessible as $some_value in the view, so your comment is not entirely accurate in this case.

Its a question of HOW its available in the view which makes all the difference.[/quote]

The comment is accurate. The variable is available in the view because you are passing the $data array to the view function which then makes it available in the view.
