How to dynamically generate friendly URLS in .htaccess using query string?

Question

I have reviewed similar questions on SO and cannot find one that fits my needs so this is not a duplicate.

I have a simple php page called top.php. I pass a parameter in the url like so: top.php?n=100.

In my .htaccess file I use mod_rewrite to change the url to top-100. Simple. But what I want to do is not have to hard code every possible url for any number passed as a parameter. Let me elaborate:

top.php?n=5 | rewrite to top-5

top.php?n=3 | rewrite to top-3

top.php?n=10 | rewrite to top-10

And so on.

So how do I create a rewrite using the query string parameter to dynamically generate the friendly url?

try a regular expression, something like top.php\?n=([0-9]+) | top-$1 — ArtisticPhoenix

You can use these rules in your .htaccess:

RewriteEngine On

RewriteCond %{THE_REQUEST} /top\.php\?n=(\d+) [NC]
RewriteRule ^ /top-%1? [R=301,L,NE]

RewriteRule ^top-(\d+)/?$ top.php?n=$1 [L,QSA,NC]
