this won't work if he has the same quantity for several keys, I think
Yes, you are correct. If that is the case, then you would just need to
change the following line
$tmpArray[$elArray['quantity']] = $elKey;
to
$tmpArray[$elArray['quantity']][] = $elKey;
then change logic in this loop:
foreach( $tmpArray as $elKey ) {
to handle the additional array. If additional sorting needs to occur for
those keys that have the same quantity then I think recursion will be in
order.
thnx,
Chris
