Way to output tags, entry id and associated entry creator

Hi Guys,
In php how do I output entry tags, entry id and the associated user in one call so that my output is:

Tags: tag1, tag2.
Entry ID: entryid
Creator: creator

I expect it’s some fusion of

$result = $client->baseEntry->listAction($filter, $pager);


$result = $client->user->listAction($filter, $pager);

Trying to update the creator/user based off a corresponding entry tag value.
Whats the disctinction between creatorid and userid incidentally for a video?
