Question

I am stuck with a problem . I have an json array which contains categories,I need the array should be sorted alphabetically based on the category name. Here is my code.

Controller

$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));

View page

                            $options = array();
                                foreach ($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>

$model

Array

    [0] => Array

                (
