Answer 1

Using .htaccess:

RewriteCond %{HTTP_HOST} !^www\.yourdomain\.com 
RewriteRule (.*) http://www.yourdomain.com/$1 [R=301,L]

Answer 2

See the following for subdomain part if you are on Apache:

1. You need to create a wildcard domain on your DNS server *.website.com
2. Then in your vhost container you will need to specify the wildcard aswell *.website.com - This is done in the ServerAlias http://httpd.apache.org/docs/1.3/mod/core.html#serveralias

Then you will want to use a rewrite rule similar to the one posted by pritaeas or get the domain with you PHP script and redirect based upon it.

$url = substr($_SERVER['SERVER_NAME'], 0, strpos($_SERVER['SERVER_NAME'], '.'));
header("Location: http://mydomain.com/$url");
