Sorting an array

Hello.

I to create an array, I place this line in three different mySQL table queries:

------------------------------------------------------
$list[] = array("tstamp" => $row[TSTAMP], "title" => $row[TITLE], "notes" => $row[notes]);
------------------------------------------------------

Now I have an array with 40 items, and I want to sort them in ascending order by tstamp (an integer).

I looked at the PHP manual pages, but got confused by the many sorting functions:
arsort(), asort(), ksort(), natsort(), natcasesort(), rsort(), usort(), array_multisort(), and uksort().

What is the easiest way to sort this array by tstamp?

The following code should do what you want

// define you sorting function
function mycmp($a,$b) {
    if ($a['tstamp'] == $b['tstamp']) {
        return 0;
    }
    return $a['tstamp'] > $b['tstamp'] ? 1 : -1;
}

usort($list, 'mycmp');
