How to redirect a subdomain to one page using htaccess?

Question

htaccess

There is a site: site.ru
There is a subdomain for this site: sub.site.ru
There are pages: index.php, sub.php
htaccess for the main site is configured as follows (works as it should):

RewriteRule ^status/([^/]+)/?$ index.php?action=weekly&status=$1 [L]
RewriteRule ^status/?$ index.php?action=weekly [L]

When you enter site.ru/status/ - opens the same as site.ru/index.php?action=weekly
When you enter site.ru/status/1/ - opens the same as site.ru/index.php ?action=weekly&status=1
This part works great!
The task is to connect ONE page to the subdomain - sub.php
What should happen:
sub.site.ru - opens the same as site.ru/sub.php?action=weekly
sub.site.ru/1/ - opens the same just like site.ru/sub.php?action=weekly&status=1
Is it possible to implement this?
If yes, then I ask for your help.
What I have tried:

RewriteCond %{HTTP_HOST} ^sub\.([^/]+)\.ru/? [NC]
RewriteRule ^(.*)/([^/]+)/?$ sub.php?action=weekly&status=$1 [L]
RewriteRule ^(.*)/?$ sub.php?action=weekly [L ]

When I go to sub.site.ru - opens sub.php?action=weekly (correctly, it works)
BUT when I try to go to sub.site.ru/1/ - opens as before sub.php?action=weekly, and should open sub.php?action=weekly&status=1

Answer 1

well, for starters, a little theory
? - and then this is a GET parameter, it is not part of the RequestURI and, as a result, is not visible to them at all, so redirects using GET parameters need to be done differently, and in addition, escape special characters, they are for this

they won't die from it for sure.
Thirdly, you are trying to write CNC - I recommend not to invent a bicycle, but to use it.
Well, let's find out.

RewriteCond %{HTTP_HOST} ^(www\.|)sub\.(.+) [NC]
#Если хост www.sub или sub.и далее хотябы один символ, плюс все регистронезависимое
RewriteRule ^(.*)$ http://sub.php\?action\=weekly\&status\=$1? [L]
#то выделяем все что там после домена в группу1 и не забывая экранировать спецсимволы подставляем в урл, плюс в конце стоит вопрос, это блядство удалит гет параметры   выставленные до этого ;)

If you need to use the GET parameter in this url, then
it will be possible to Catch it already through
Collect it in the same way in a group and substitute it in the steering wheel, but not $2 but %2
