Question

I want to sort a multidimensional array from z to a.
I can already sort it from a to z with this function:

function aasort (&$array, $key) {
                $sorter=array();
                $ret=array();
                reset($array);
                foreach ($array as $ii => $va) {
                    $sorter[$ii]=$va[$key];
                }
                asort($sorter);
                foreach ($sorter as $ii => $va) {
                    $ret[$ii]=$array[$ii];
                }
                $array=$ret;
            }

But how do i reverse it?

Answer 1

use rsort for reverse sorting

foreach ($array as $ii => $va) {
    $sorter[$ii]=$va[$key];
}
rsort($sorter);
foreach ($sorter as $ii => $va) {
    $ret[$ii]=$array[$ii];
}
