Sorting array by count of subarray

Question

I have an array looking like this:

Array(
   [\'some_first_category\'] => Array(
            [\'some_first_name\'] => Array(
                                   


        

Answer 1

Using uksort:

uksort($yourArray, function($a, $b) { return count($b) - count($a); });

Using array_multisort:

array_multisort(array_map('count', $yourArray), SORT_DESC, $yourArray);

and you can see uasort as well

best of luck :)
