show active AND expired in product IDs for users

I'm using code to create reports and print info.

I use the following format which works:-

$ticketlist = $user->getActiveProductIds();
if (in_array("38",$ticketlist, TRUE)) { ... do something ... }

however, I need to be able to check if products belong to user whether they are active or expired.

How could I modify the above code to check for a product ID belonging to a user irrespective of whether it is active or expired?

is there a function like $user->getActiveOrExpiredProductIds(); ?

or could I combine a active and expired array to make an ActiveAndExpired array?

Thanks

Don't have an answer for you- looking for it myself.
