How to get htacces GET parameters?

Question

htaccess

I did this, you need to get the id the site opens and works along the path site.ru/mod/
RewriteRule ^mod(/?)+$ index.php?do=mod&id=$1 [L]
I automatically set the first parameter and want to get the second one, how can I pass it?
I tried these methods but they give errors
site.ru/mod/1
site.ru/mod/id/1
site.ru/mod?id1
site.ru/mod/id1
I wanted it to be transmitted like this site.ru/mod/1

Answer 1

RewriteRule ^mod/([0-9]+)(/?)$ index.php?do=mod&id=$1 [L]

Found if anyone needs

Answer 2

I read it five times before understanding what you want, and then I understood it from the answer of my colleague.
Here's another option for you if the first one doesn't work, on some web servers you need to comment on the special character "?"
well, a slightly different post

RewriteRule ^mod/([0-9]1,)(/?)$ index.php\?do=mod&id=$1 [L]
