2 ways of defining own rules in validation? - El Forum - 04-17-2010

according to this article:
http://www.phpandstuff.com/articles/codeigniter-doctrine-scratch-day-3-user-signup-form
it seems to be 2 ways of defining an own validation rule:
function[field]
and
callback_function
what's the difference and when should you use which one?

The first method using a callback, is a function on the controller itself and the second one is extending the form_validation library. I don't know if there is a rule on using one or another. If I use only 1 specific validation rule on one controller, I use a callback but if I have a rule that many controllers use, I extend the library.
