Wildcard DNS, Subdomain and mod rewrite

rewrite any.site.com -> /root-of-site/test.php?subdomain=any

[iProgram]

My DNS setting looks like this:

site.com A: 123.123.123.123
www. A: 123.123.123.123
*. A: 123.123.123.123

site.com is IP based site. Both www.site.com and anything.site.com point to same IP (123.123.123.123). There are /index.html and /test.php under root folder of site.com.

I want

1. site.com 301 redirect to www.site.com, and
2. www.site.com shows /index.html and
3. others.site.com shows /test.php?subdomain=others
4. others.site.com/file1/file2.html shows /file.php?subdomain=others&param1=file1&param2=file2

How to create the /.htaccess file?

TIA
