how does array_multisort work?(!??)

Hi, all -- I have an array like $a = array ( '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. For a given source array kind of like $a bookmark How To Bookmark This is all about bookmarking. add Adding Pictures Let's talk about pictures. zebra Caught You Here This is about zebras but it has a surprise title. then I want $a add Adding Pictures Let's talk about pictures. zebra Caught You Here This is about zebras but it has a surprise title. bookmark How To Bookmark This is all about bookmarking. after sorting. Will array_multisort sort on an arbitrary key of a multidimensional array, or does it just sort multidimensional arrays but only in key index priority? Barring that, I imagine I'd have to either ensure that the array is constructed in the proper order or make an index of titles => keys so that I could sort that and then pull the key out to display the list. Bleah. Once again it would probably be easier to just lay out a DB schema!
