array_multisort accepts column arrays but here you try to sort row based
arrays.
try this:
<?
class ArrayUtility
{
/* Sorts an array by a member */
static private $sortMember;
static function sortByMember(&$array, $member)
{
self::$sortMember = $member;
usort($array, array('ArrayUtility', 'compareMember'));
}
static function compareMember($a, $b)
{
return $a[self::$sortMember] > $b[self::$sortMember];
}
}
ArrayUtility::sortByMember($array, 'quantity');
?>

Jon, I would suggest that you should have a look at the function
"array_multisort". See the manual for details on what this function is
capable of.
