Answer 1

You can't.*

If your functions are so universal as to be used outside of views, create them in bootstrap.php or make a custom library/class in the libs/ directory.

* _{You can load anything anywhere using App::import('Helper', 'NameOfHelper') or ClassRegistry::init, but you really shouldn't. The point of MVC separation is to keep your app well organized.}
