Automatically sort all Arrays in controller when getting from database PHP -

so have controller passes associative array called $pagedata view. inside array 3 more associative arrays, , view renders 3 select elements array data options. want sort 3 arrays don't want write sort 3 times here or add order_by query methods, because there dozens of similar pages , don't want write hundreds of sort method calls. told solve in constructor. wondering if there's oop solution lets me automatically sort child arrays inside $pagedata.

class sku extends ci_controller {     protected $pagedata = array();      public function __construct()     {         parent::__construct();         $this->load->model('mc');     }      public function inventory()     {         $this->pagedata['class_ids'] = $this->mc->get_class_ids();         $this->pagedata['retail_readys'] = $this->mc->get_all_retail_ready();         $this->pagedata['statuses'] = $this->mc->get_all_status();     } } 

edit: i'm exploring using arrayobject or wrapping $pagedata in object , watch changes.

ok painfull codeigniter yes kind of solution

public function __construct()     {         parent::__construct();         $this->load->model('mc');         $class_ids = $this->mc->get_class_ids();         $class_ids = $this->sortascending($class_ids, $key);         $this->pagedata['class_ids'] = $class_ids;          $retail_readys = $this->mc->get_all_retail_ready();         $class_ids = $this->sortascending($class_ids, $key);         $this->pagedata['class_ids'] = $class_ids;          $statuses = $this->mc->get_all_status();         $statuses = $this->sortascending($class_ids, $key);         $this->pagedata['statuses'] = $statuses;     }  function sortascending($accounts, $key) {     $ascending = function($accounta, $accountb) use ($key) {         if ($accounta[$key] == $accountb[$key]) {             return 0;         }         return ($accounta[$key] < $accountb[$key]) ? -1 : 1;     };     usort($accounts, $ascending);      return $accounts; }  public function inventory() {     // values     //$this->pagedata['class_ids'] = $this->mc->get_class_ids();     //$this->pagedata['retail_readys'] = $this->mc->get_all_retail_ready();     //$this->pagedata['statuses'] = $this->mc->get_all_status();     $this->load->view('index',$this->pagedata); }   public function another_function() {     // values     //$this->pagedata['class_ids'] = $this->mc->get_class_ids();     //$this->pagedata['retail_readys'] = $this->mc->get_all_retail_ready();     //$this->pagedata['statuses'] = $this->mc->get_all_status();      $this->load->view('another page',$this->pagedata); }
