Sorting Associative Array - multiple keys

[cmayo]

Does anyone know of an arry sort that'll let me sort an associative array on multiple keys at multiple levels? I have an array of events, and each event (below) contains multiple keys and sub-arrays. I need to sort the entire event array based on the sorts shown below.

I imagine there are some pre-written routines or classes that'd let me do something like this, but I don't seem to be able to turn anything up.

EVENT Array
(
    [84815] => Array [b](84815 is event ID)[/b]
        (
            [date_time] => 2006-02-22 19:30:00 [b]<- FOURTH SORT ASC[/b]
            [date] => 2006-02-22
            [time] => 19:30:00
            [status] => 6
            [status_text] => Complete
            [away] => Array
                (
                    [id] => 716
                    [name] => Molina
                    [score] => 3
                    [district_id] => 172
                    [district_name] => 9-5A
                    [district_dist] => 9
                    [district_class] => 5A
                )

            [home] => Array
                (
                    [id] => 47
                    [name] => W.T. White
                    [score] => 4
                    [district_id] => 172
                    [district_name] => 9-5A
                    [district_dist] => 9 [b]<- SECOND SORT - DESC[/b]
                    [district_class] => 5A [b]<- THIRD SORT - ASC[/b]
                )

            [site] => 1824
            [site_name] => Forester
            [winner] => 
            [type] => 10 [b]<- FIRST SORT - CUSTOM (10,4,27,etc.)[/b]
            [type_description] => District
        )

This sounds to me like an application for usort():

http://www.php.net/manual/en/function.usort.php

usort() sorts an array using a user-specified sorting function.

uasort() for associative arrays so you can be sure to maintain index association, no?
