Pretty URLs and dynamic Vars
===

I am in the outlining phase of constructing a Routing system for a PHP Framework I am building.

I will need to use mod rewrite, for pretty urls. I got that part covered.
But say I want to make a page with the url like:

www.domain.com/news/10(News-id)/

and I want this dynamic variable ( This news id ) to have a name when rewriting.

What I want to achieve is;

Frameworks routes to news controller, and passes 10 as argument as:
$args = array ( 'news_id' => 10 )
