Maybe I just am not understanding you correctly, but aren't they the
same thing?
In PHP:
$ar['m']['n'] = 1;
is equivalent to:
$ar = array('m' => array('n' => 1));

Both can be referenced as $ar['m']['n'].

Off the top of my head, the most relevant example from that php manual
page would be Example 3. Sorting database results. It sounds like you
want to essentially sort a 'table' of data by one of the columns. The
concepts of that example should point you in the right direction.
Unless, as I said, I am completely misunderstanding your question.
