NGINX rewrite rule using two variables

Question

I would like to achieve this but don't know how, or if it is possible:

web.com/anything => if web.com/show.php?query=anything

web.com/anything/something => if web.com/show.php?query=anything&query2=something

I mean , if there's only one variable it rewrites to web.com/variable

If there's a second variable, the first one turns into a folder now => web.com/variable/variable2

Answer 1

Just did it !!

Was more simple that I've imagined..

rewrite ^/([a-zA-Z]+)/([a-zA-Z]+)$ show.php?query=$1&query2=$2 last;
