Return value

Note: The [0] element of the array returned by this function is the tern you reference when you call the function. E.g.
$myarray=taxonomy_get_parents_all(200);
print $myarray[0]['tid'];

Results: 200

To be more accurate the whole

To be more accurate the whole array is flipped. So if you have structure like A -> B -> C -> D and you are trying to get parents for D you'll end up with

array(
0 => D (term object),
1 => C (term object),
2 => B (term object),
3 => A (term object)
);
