Give it a try

$array = array(array_values($array),array_keys($array));
array_multisort($array[0], SORT_DESC, $array[1], SORT_ASC);
$sorted_array = array_combine($array[1],$array[0]);

Take a look at ksort

http://php.net/manual/en/function.ksort.php

For example...

<?php
$fruits = array("d"=>"lemon", "a"=>"orange", "b"=>"banana", "c"=>"apple");
ksort($fruits);
foreach ($fruits as $key => $val) {
  echo "$key = $val\n";
}
?>

Output

a = orange

b = banana

c = apple

d = lemon
