php - Json数组在yii1中按字母顺序排序

Question

我遇到了一个问题。我有一个包含类别的 json 数组，我需要该数组应根据类别名称按字母顺序排序。这是我的代码。

• 控制器

  $post = file_get_contents("............");
  $model = CJSON::decode($post, true);
  
          function cmp($a, $b)
          {
              //echo "<pre>  a: ";print_r($a);die;
              return strcmp($a["name"], $b["name"]);
          }
          usort($model, "cmp");
          $this->render('index',array('model'=>$model));

                                  foreach ($model as $user) :
  
                                      foreach($user as $use):
  
                                          $options[$use['id']] = $use['name'];
  
                                      endforeach;
                                  endforeach;
  
                          echo CHtml::dropDownList('mySelect', 'name', $options,array('prompt'=>'------Select--------'));
  
  
                      ?>
              </div>
          </div>
