Mod_Rewrite set subdomain and directory to GET variable

Question

I have programmed a website on which I want to be multilingual, individual languages ​​should be accessible through a subdomain, for example, en.example.com, de.example.com, etc.

Also, I already have a rewrite to set the “directory” as a GET variable, which changes example.com/name to example.com/index.php?page=name.

No matter what I tried, I see no way to correctly combine the two codes that I need to use with these problems. Each of them works by itself, I only need a method to combine both, so en.example.com/name will be rewritten to example.com/index.php?page=name&lang=en

What I use for directories for GET variables

RewriteRule ^/?(\w*)/?$ index.php?page=$1 [L] 

What I found for subdomains for GET variables

 RewriteCond %{HTTP_HOST} !^www\. RewriteCond %{REQUEST_URI} !index\.php RewriteCond %{HTTP_HOST} ^(.+?)\.example\.com$ RewriteRule .* /index.php?lang=%1 [L] 

Answer 1

You just need to combine your 2 rules

 RewriteEngine On RewriteCond %{HTTP_HOST} ^((?!www\.)[^.]+)\.example\.com$ RewriteCond %{REQUEST_URI} !^/index\.php$ [NC] RewriteRule ^(.*)$ /index.php?page=$1&lang=%1 [L]
