Redirect everything to index.php

Question

I'm trying to do clean URLs by exploding $_SERVER['REQUEST_URI'] and then switching between the results.

However, once a user goes outside index.php, I'm assuming I need to redirect them back to index.php in order to process the URL they want to reach. How can I accomplish this?

So for instance, if the user goes to www.domain.com/home/johndoe/... I'd like index.php (domain.com/index.php) to be hit so that it can process the /home/johndoe/ via request_uri.

.htaccess:

RewriteEngine on
RewriteBase /
RewriteCond  %{REQUEST_FILENAME} !-f
RewriteCond  %{REQUEST_FILENAME} !-d
RewriteRule  ^(.*)$ index.php?param=$1 [QSA,L]
