Unfortunately, it's really up to the web server, not PHP. Depending on if you use Apache or something else, it has to do this before your script is executed. I use mod_rewrite, and an example rewrite rule looks like this:

    RewriteEngine On
    RewriteBase /
        RewriteCond %{REQUEST_FILENAME} !-f
        RewriteCond %{REQUEST_FILENAME} !-d
        RewriteRule ^(.*)$ /index.php/%{REQUEST_URI} [PT,L]

The above rule basically says if the URL is a valid path to a real file or directory, load it. Otherwise, run it through index.php.
