Studying the above functions and trying to get them to work, when I was in a sub category, most of the time it returned 0. I believe this is because of the else statement, which is stopping the for loop from looping.

Anyway, I wrote my own function… it returns the parent category ID for any category down to one level.

function get_parent_category() {
	global $cat;
	foreach ((get_the_category()) as $cato) {
		if($cat==$cato->cat_ID) {
			if($cato->category_parent==0)
				return $cat;
			else
				return $cato->category_parent;
		}
	}
	return $cat;
}
