Answer 1

It is kinda a big workaround, but it does work:

$a = array(70 => 1 ,82 => 5  ,61 => 3 ,55 => 1 ,34 => 2 ,53 => 2 ,21 => 4 ,13 => 5);
$b = max($a);
$c = min($a);
$d = 0;
$sorted_list = array();
while($b >= $c){
    foreach($a as $key => $value){
        if($value == $b){
            $sorted_list[$key] = $value;
        }
    }
    $b--;
}

vardump output:

array(8) { [82]=> string(1) "5" [13]=> string(1) "5" [21]=> string(1) "4" [61]=> string(1) "3" [34]=> string(1) "2" [53]=> string(1) "2" [70]=> string(1) "1" [55]=> string(1) "1" }
