In .htaccess you can do the following

RewriteEngine on
RewriteCond   %{HTTP_HOST}                 ^[^.]+\.domain\.com$
RewriteRule   ^(.+)                        %{HTTP_HOST}$1          [C]
RewriteRule   ^([^.]+)\.domain\.com(.*)    http://www.domain.com/$1$2

This rewrites http://username.domain.com/anypath
internally to http://www.domain.com/username/anypath
