Reverse sorting array inside an object based on an subarray's value in PHP

Question

My object looks like this:

object(stdClass)#1 (1) {
  ["drives"]=>
  array(2) {
    [0]=>
    array(2) {
      ["drive"]=>
      string(11) "Drive1"
      ["features"]=>
      array(4) {
        ["statusCode"]=>
        int(1)
        ["UsedValue"]=>
        string(4) "222"
        ["TotalValue"]=>
        string(5) "22222"
        ["smart"]=>
        string(1) "0"
      }
    }
    [1]=>
    array(2) {
      ["drive"]=>
      string(5) "Drive2"
      ["features"]=>
      array(4) {
        ["statusCode"]=>
        int(0)
        ["UsedValue"]=>
        string(6) "2222"
        ["TotalValue"]=>
        string(7) "222222"
        ["smart"]=>
        string(1) "0"
      }
    }
  }
}

How can I sort the array drives based on the value of statusCode that's inside the subarray features, from the highest number to the lowest?

I need to preserve this structure, I can't put the statusCode in the Drive array.

are there always only two elements within the `drives` array? — RomanPerekhrest, May 04 '16 at 08:30
You can use own comparison function: http://php.net/manual/en/function.uasort.php — dzsubek, May 04 '16 at 08:36

Use uasort(to preserve keys) function for such case:

// $obj is your initial stdClass object
uasort($obj->drives, function($a,$b){
    return $b['features']['statusCode'] - $a['features']['statusCode'];
});
