Question

I want to make this url redirect using .htaccess (linux/apache) ..

I want to keep “as is” all calls for www sub domain like this

www.example.com/index.php
www.example.com/test.php?id=1&name=a
www.example.com/whatever.php?whateverurl=xxxx

but I want to redirect all wild card urls like this with the sub domain as extra variable to current unlimited-whatever url variables

for example

xxx.example.com -> example.com/?subdomain=xxx
yyy.example.com/index.php -> example.com/index.php?subdomain=yyy
whatever.example.com/test.php?var=1 -> example.com/test.php?subdomain=whatever&var=1
whatever.example.com/whatever.php?var1=1&var2=2 -> example.com/whatever.php?subdomain=whatever&var1=1&var2=2

is this possible?

Thank you

Once you set up your Wildcard DNS Record you should make your .htaccess file:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^www.example\.com$
RewriteRule ^(.*)\??(.*)?$ $1?host=%{HTTP_HOST}&%{QUERY_STRING} [L] [L]

This rule works, although it will provide you the whole host, rather than just the subdomain, which you’ll have to parse in your PHP.
