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?

>>5
How to do it isn't what's the problem. I just want to know whether this works on all servers with php, or if some configurations might show 404s etc. when using links in the format of >>4. But thanks for pitching in.
