File makeDirectory

I can make a Folder Successfully when a user create his account based on his chosen username but I also want to instruct make sub folders for instance when you create an account with username "john" a folder is created called "john" what about if I want to create sub folders for this user.

So basically when your username is "john" I want to create sub folders like :

john/folder1

john/folder2

john/folder3

here is the main folder code line :

File::MakeDirectory('/home/vagrant/Code/laravel/UserFolders/' . $data['username']);
