It's built in. array_multisort.

(I may not be using this function the best way, and if I'm missing a
simpler way to do this then hopefully someone will point that out. This
function does somewhat baffle me, but by trial and error I have found
that this works.)

While building this structure - create the $date array:
$item[0]['title']
$item[0]['content']
$item[0]['date']

$date[0] = $item[0]['date']

$item[1]['title']
$item[1]['content']
$item[1]['date']

$date[1] = $item[1]['date']

etc...

Then this will work

array_multisort($date, SORT_DESC, $item);
