stdClassオブジェクトで配列を並べ替える

Question

私はこの配列をUbercartのorder.tpl.phpファイルの各stdClassオブジェクトの[title]でソートしようとしています。私はちょうど通常の並べ替えをしてみましたが、それらはすべてstdClassオブジェクトなので何もしません。

<pre>Array 
(
[0] => stdClass Object 
    (
     [order_product_id] => 1157

       [restrict_qty] => 1 
       [module] => uc_product

     [order_uid] => 13 
    )

    (

       [module] => uc_product 
      ) 

     [order_uid] => 13 
    ) 

[6] => stdClass Object 
    (
     [order_product_id] => 1163 
     [order_id] => 142 
     [nid] => 33 
     [title] => White River Forest Non-motorized Recreation Access Permit for Individuals and Release of Liability

       [module] => uc_product 
      ) 

     [order_uid] => 13 
    ) 
)</pre> 

これはorder.tpl.phpに

<pre>php if (is_array($order->products)) { 
         $context = array(
          'revision' => 'formatted', 
          'type' => 'order_product', 
          'subject' => array(
          'order' => $order, 
         ), 
         ); 
} 
</pre> 

Answer 1

を、それを制御するコード私はusort()が動作するはずだと思うです：

function sortByTitle($a, $b){ 
    return strcmp($a->title, $b->title); 
} 

usort($theArray, 'sortByTitle'); 

あなたが作るために、いくつかのチェックでスローすることをお勧めします実際にはtitleのメンバーが存在することを確認してください。
