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?

Learn not to use shitty hosts, write in Django, host on Google App Engine, and then go away. Or, you know, stay, or whatever, really. You go do that, and then you're okay by me.
