if($topic=mgd_list_topics($parent_topic_id))
while($topic->fetch())
{
echo $topic->name."<br>";
if($article=mgd_list_topic_articles($topic->id))
while($article->fetch())
{
echo $topic->name." - ".$article->name;
}
echo "<br>";
}
That's it !
If you want to display recursively an entire topic tree, use a recursive
function which display the topic->name and all its articles, and that call
itself with the subtopic->id.

mgd_list_topics doesn't return an array, but an object with the fetch()
function embedded into it. That function allows you to get all the records
one by one in a while loop.

the database ids ARE NOT sequencial, so the only way is to use the fetch()
function.
