How to get Value for “Root Path for this User Role”?

Hello again,

I am working on getting your Plugin to understand Ultimate Members User Roles better ?? It does already, but one thing I need to know:

On Settings -> User Role Restrictions, I can see and change “Root Path for this User Role”. I need this value for another PHP script, because I must match the Directory to the User Role.

When searching the Database, I see one Field in wp_options: njt_fs_settings, and this contains all stored Information within a serialized String.
Of course I could try to split that string and somehow make my way…

…but maybe there is a better method to get the root Path for a certain User Role?

Tried $arrRestrictions[$firstKeyRestrictions][‘private_folder_access’], but it returns nothing…

Thanks!
