hi,
I have the following array, which I need to sort by quantity...
Array

[quantity] => 4

[3388] => Array

I need to keep the indexes if poss.
Many thanks,

This works for me:
function cmp($a, $b)
{
$aq = $a['quantity'];
$bq = $b['quantity'];
if ($a == $b) {
return 0;
}
return ($aq < $bq) ? -1 : 1;
}
uasort($data, "cmp");
To reverse the sort order: return ($aq > $bq) ? -1 : 1;

Re: [PHP] sorting multi array
array_multisort accepts column arrays but here you try to sort row based arrays. try this: $b[self::$sortMember]; } } ArrayUtility::sortByMember($array, 'quantity'); ?> Am 25.04.2007, 12:36 Uhr, schrieb Frank Arensmeier <[EMAIL PROTECTED]>: Jon, I would suggest that you should have a look at the function "array_multisort".

Re: [PHP] sorting multi array
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

This may not be the most elegant solution. Let's call your array
$origArray
$tmpArray = array();
foreach( $origArray as $elKey => $elArray ) {
$tmpArray[$elArray['quantity']] = $elKey;
}
if( ksort( $tmpArray )) {
$sortedArray = array();
foreach( $tmpArray as $elKey ) {
$sortedArray[$elKey] = $origArray[$elKey];
}
echo 'Original: ' . print_r( $origArray, TRUE ) '';
echo 'Sorted: ' . print_r( $sortedArray, TRUE ) '';
} else {
echo 'Sorry, couldn\'t sort';
}
thnx,
Chris
