Question

I am trying to order the elements of an array by the following two ways:

• Sort by key length (smallest should go first) – See here
• Max value should go first

To sort by key length I use this:

    function sortByLength($a,$b){
      if($a == $b) return 0;
      return (strlen($a) < strlen($b) ? -1 : 1);
    }

    uasort($deals_tag,'sortByLength');

And the array is sorted that way:

Array
(
 [/merchantProductFeed] => 1
 [/merchantProductFeed/merchant] => 1
 [/merchantProductFeed/merchant/prod/text] => 158
 [/merchantProductFeed/merchant/prod] => 158
)

I want it to be sorted like this:

Array
(
 [/merchantProductFeed/merchant/prod] => 158
 [/merchantProductFeed/merchant/prod/text] => 158
 [/merchantProductFeed] => 1
 [/merchantProductFeed/merchant] => 1
)

Notice that first the array is sorted by key length and then by max value.

I don’t know how to do that.

Any help would be highly appreciated! Thank you!

updated: you can use array_mulitsort. try

$k= array();
$v = array();

foreach($deals_tag as $key => $value){
    $k[] = $key;
    $v[] = $value;
}

array_multisort($v, SORT_DESC, $k, SORT_ASC,  $deals_tag);
