Multidimensional array sort by date

[eluser]pickupman[/eluser]
@jprateragg has the best of doing it in the model, provided that a UNION will work. Otherwise you can use [url="http://php.net/manual/en/function.usort.php"]ursort()[/url]. Here's a quick comparison function that will work on your array.

Code:

function sort_by_date($a, $b)
{
if ($a->added_date == $b->added_date)
{
  return 0;
}

return ($a->added_date < $b->added_date) ? -1 : 1;
}

usort($yourData, 'sort_by_date');
