Redirect subdomain including all its subdirectories to root

I've got it working in that it redirects the subdomain itself, but it doesn't redirect any of the subdirectories for that subdomain.

For example:

sub.domain.com redirects to www.domain.com

but:

sub.domain.com/directory/ doesn't redirect

Here is my code:

RewriteCond %{HTTP_HOST} ^sub\.domain\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.sub\.domain\.com$
RewriteRule ^/?$ "http\:\/\/www\.domain\.com" [R=301,L]

Your pattern in the rewriting rule matches only the root itself, so it does not get applied to anything else. Have a try with this modified version: 

RewriteEngine on
RewriteCond %{HTTP_HOST} ^sub\.example\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.sub\.example\.com$
RewriteRule ^ http://www.example.com/ [R=301]

This obviously redirects all requests to the root of the www.example.com host. In case you want to preserve the actual path requested you will need to capture it: 

RewriteEngine on
RewriteCond %{HTTP_HOST} ^sub\.example\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.sub\.example\.com$
RewriteRule ^/?(.*)$ http://www.example.com/$1 [R=301]

That rule will work likewise in the http servers host configuration or inside a dynamic configuration file (".htaccess" file). Obviously the rewriting module needs to be loaded inside the http server and enabled in the http host. In case you use a dynamic configuration file you need to take care that it's interpretation is enabled at all in the host configuration and that it is located in the host's DOCUMENT_ROOT folder.

And a general remark: you should always prefer to place such rules in the http servers host configuration instead of using dynamic configuration files (".htaccess"). Those dynamic configuration files add complexity, are often a cause of unexpected behavior, hard to debug and they really slow down the http server. They are only provided as a last option for situations where you do not have access to the real http servers host configuration (read: really cheap service providers) or for applications insisting on writing their own rules (which is an obvious security nightmare).
