Re: [PHP] sorting multi array

[[EMAIL PROTECTED]]

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.

   [2408] => Array
       (
           [name] => Havaianas Top Pink Crystal
           [size] => 5 (37/38)
           [quantity] => 4
       )

       (
           [name] => Havaianas Brazil Silver
           [size] => 6/7 (39/40)
           [quantity] => 6
       )

   [2666] => Array
       (
           [name] => Havaianas Brasil Black
           [size] => 8/9 (41/42)
           [quantity] => 1
       )

   [3210] => Array
       (
           [name] => Havaianas Margaridas Yellow
           [size] => 5 (37/38)
           [quantity] => 1
       )

   [2552] => Array
       (
           [name] => Havaianas Flash White
           [size] => 5 (37/38)
           [quantity] => 1
       )
)

I need to keep the indexes if poss.

Many thanks,

jon
