Both Smarty and Twig compile your template files down to php templates.
Zend_View, Aura.View, and Symfony's php view include php files directly
without a compilation phase.

I don't get how I would write a "simple controller class layer to
operate on top of it".

Does the inclusion limitation apply to just the script in question, or
the entire call stack?

A simplified example:
index.php -> FrontController.phpp -> Controller.phpp -> View.phpp ->
can't include template.phtml

index.php -> FrontController.phpp -> Controller.phpp -> View.php -> can
include template.phtml ?
But I can't do require_once('View.php') in the controller.

If there's an autoloader involved, it would have to be set up in
index.php, and would also have to be .php so that it can include both
file types.

index.php -> FrontController.phpp -> Controller.phpp -> Autoloader.php
-> can include View.php ?

But will that work since there are .phpp files above it in the call stack?

Cheers,
David
