Question

我遇到了问题。我有一个包含类别的json数组，我需要根据类别名称按字母顺序排序数组。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));

                            $options = array();
                                foreach ($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
        (
            [0] => Array
                (
                    [id] => 1
                    [name] => SMALL PATCHES
                )

            [1] => Array
                (
                    [id] => 2
                    [name] => BIG PATCHES
                )

            [2] => Array
                (
                    [id] => 3
                    [name] => CUSTOM PATCHES
                )

            [3] => Array
                (
                    [id] => 4
                    [name] => EVENT PATCHES
                )

            [4] => Array
                (
                    [id] => 5
                    [name] => BLANK PATCHES
                )

            [5] => Array

我得到了答案，我做了一个小改动

控制器

$post = file_get_contents("...........");
        $model = CJSON::decode($post, true);

        function cmp($a, $b)
        {
            return strcmp($a["name"], $b["name"]);
        }
        uasort($model['categories'], "cmp");
        $this->render('index',array('model'=>$model));
