You cannot mix-and-match twig and php in a single Response (to do so would be circumventing part of the point of twig, which is to prevent designers from creating too much logic in the view).

I think the Symfony documentation should/could be clearer about this (at the moment it basically says "enable them both and do what you like").

If you embed another controller then you should be able to serve up a different Response and that Response can be php based.
