Re: how does array_multisort work?(!??)

Hi, all -- I have an array like $a =

      'key' =>
        array

          'title' => "Topic Title",
          'content' => "Topic Content",
        ),
        ...
    ) ;

and I'd like to sort the whole thing not on the keys but on the titles. It sounds like array_multisort should do exactly what I want, but I can't seem to get it to work.

usort is what you need: function cmp($a, $b) { if ($a['title'] == $b['title']) {

       return 0;

} return ($a['title'] < $b['title']) ? -1 : 1; } usort($a, "cmp");
