How can I delete a user from entire multisite nework

Question

I'm making a front-end user delete button but it only removes the user from the current installation and I need to remove them from the entire multisite network so they are able to sign up again with the same email if they decide. Is there a way to do this?

$userid = get_current_user_id();
wp_delete_user( $userid );

You would want to use wpmu_delete_user:

$userid = get_current_user_id();
wpmu_delete_user( $userid );

Deletes a user from the network and removes it from all sites.
