Using htaccess for Multiuser PHP Scripts

Hey guys,
I am a little concerned about something I've been searching for a long time.

In a directory in my server I have a .htaccess file containing these lines:

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule . - [L]
RewriteRule  ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

Code (markup):

This code makes files that are on the root of the directory to be available if browsed on subfolders...

For example http://www.server.com/user1/index.php will output the same as http://www.server.com/index.php.

What I am trying to do is to make the code to have some more functionality.

I would like the code to be able to mimic files from other directories, not just the root one. Aditionally I would like the code to use the custom directories as a variable.

For example http://www.server.com/user1/page.php should output the same in http://www.server.com/secret/ss-page.php?mid=user1.

And http://www.server.com/user1/page.php?foo=bar should output the same in http://www.server.com/secret/ss-page.php?mid=user1&foo=bar.

Another example: http://www.server.com/user1/more/page.php?foo=bar should output the same in http://www.server.com/secret/more/ss-page.php?mid=user1&foo=bar.

Thanks in advance,

This code will direct ALL requests to the file site_mod.php:

#activate mod_rewrite
	Options +FollowSymlinks	
	RewriteEngine on
	RewriteBase /

#rewrite conditions
	RewriteRule ^(.*)$  site_mod.php?$1

Code (markup):

When this code sends the request to your file, you can look at the $_SERVER["REDIRECT_QUERY_STRING"]); variable in FTP to see exactly what URL the user entered.

Then, based on the request, you either redirect them or provide them with the data. Here is an example:

//	The redirect_query string is broken into segments
	$GLOBALS["page_request"] = explode ("/", $_SERVER["REDIRECT_QUERY_STRING"]);
	
//	Requests for files in the theme directory are handled immediately
	if (strcasecmp ($GLOBALS["page_request"][0], "theme") == 0)
	{
	//	Since this site uses a global redirect, this module has to handle requests
	//	for files in the theme folder directly
		$filename = basename ($_SERVER["REDIRECT_QUERY_STRING"]);
		
		if (is_file ($_SERVER["DOCUMENT_ROOT"]."/themefiles/".$filename))
		{
		//	apparently firefox and chrome are not happy without a mime type for .css
			if (substr ($filename, -4) == ".css")
			{
				header ("Content-Type: text/css");
			}

			readfile ($_SERVER["DOCUMENT_ROOT"]."/themefiles/".$filename);
			exit;
		}

		else
		{
			header ("HTTP/1.0 404 Not Found");
			exit;
		}
	}
