Answer 1

I'm thinking...

print $arrayName[2]->user_id;

Answer 2

If you can guarantee that the array only has one item and you know the key, then go with Jonathan Sampson's solution. Otherwise if you have a few items you can loop over it like this and extract the userid for each one.

foreach ($array as $item) {
    $userId = $item->user_id;
    //do something with the userId for this item
}
