i need a feature through array. 
function getComments(){
  return array(
   "id" => 1,
   "comment" => "this is test comment",
   "favorite_users" => array(10, 15, 2, 5),
   "favorite_users_count" => count(array(10, 15, 2, 5))
  );
}

The above function, there is key "favorite_users" having values and the key "favorite_users_count" only holds count of array key "favorite_users". 

Here the key "favorite_users_count" again setting the values for count array. 

Is there any way to achieve the count calling the array key "favorite_users".


Thanks
