First off, cross-posting is rude. Don't post to more than one list at a
time. Post your question to the most relevant list first and if you don't
get help, then try another one.
As for your select statement, why do you have the select around the other
select? Why don't you just have this:
SELECT MAX(id) FROM article
As for how the result is returned, not much you can do about it. That is
the way PHP is. As a matter of fact, that is the way a vast majority of
database interaction programs are. They send an array so that the field
name can accompany it.
Only optimization you can do is fix the select statement.
