PHP GET variables

My URLs are currently way too long, so I'm thinking of using index.php as a redirect to other parts of my site. What I had in mind is www.example.com/?nigger. The thing is that I'm using free hosting (inb4 shitstorm), and I have to change hosts once in a while. Are there any server configurations (which support PHP at all) that wouldn't work with this?

What documentation? The one for PHP? Or for every server I might happen to end up using in the future?

I really don't see how SICP could help me here, but then again, I guess SICP is always related.
