Matching pretty and ugly url's with .htaccess file

Question

I use mod_rewrite and a .htaccess file with this rules

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

In index.php i echo $_GET['q'] as get(q) and $_SERVER['QUERY_STRING'] as server(qs).

When i acces a pretty URL like ../post/123 it works in get(q) and server(qs) and display: post/123 or type=post&id=123.

But when i access a URL like ../?type=post&id=1 i get nothing in get(q) but in server(qs). I also have tried

RewriteRule ^(\??)(.*)$ index.php?q=$1 [L,QSA]

in hope that it add an optional questionmark.

EDIT: As an explaination, i want to analyze everything that comes after the trailing slash of the domain. it doesnt matter if its a pretty url or an ugly one i want to handle the behavior in php.

How can i match ugly AND pretty URLS with a .htaccess file?

Thank you
