Yep, I was using array_merge and that's wrong. Im dealing with a list of 
objects so that made it a little confusing but I got it working. In this 
case I was dealing with a tree of categories where each category has a 
parent_node and the top-level categories have a parent_node of zero. So it 
was something like:

function getsubcategories($parent_id, &$list)
{
	$categories = getcategorieswithparent($parent_id);
	if ($categories != NULL)
	{
		foreach ($categories as $category)
		{
			// append object
			$list[] = $category;
			getsubcategories($category->parent_id(), $list);
		}
	}
}

getsubcategories(0, $current_list);


Im using this to populate a pulldown in a form with a nice function to 
show the pathname to each category.
