Question

我有一个来自的数组和像这样的API

 array(
    'data' => array(
        'id' => 0,
        'attributes' => array(
            'title' => 'title'
        ),
        'itemdetails' => array(
            'id' => 0,
            'attributes' => array(
                'title' => '',
                'images' => array(
                    'original' => '',
                    'thumbnails' => array(
                        'thumb',
                        'thumb'
                    )
                )
            )
        )
    )
);

所以，如果我想获得我必须做的图像

$array['data']['itemdetails']['attributes']['images']['thumbnails']

有没有办法让我能做到

$array->getImageThumbnails()

非常感谢提前！

Answer 1

我可能会后悔，但这是一个简单的实现：

class someClass {

    public $array;

    public function __construct($array) {
        $this->array = $array;
    }

    public function getImageThumbnails() {
        return $this->array['data']['itemdetails']['attributes']['images']['thumbnails'];
    }
}

然后只是：

$object = new someClass($array);
$thumbs = $object->getImageThumbnails();

一种解决方案是创建一个将在其构造函数中接受此数组的对象，并在该对象上定义所需的方法：

class MyImage {
    protected $data = array();

    public function __construct($data)
    {
        $this->data = $data['data'];
    }

    public function getImageThumbnails()
    {
        return $this->data['itemdetails']['attributes']['images']['thumbnails'];
    }
}

获得数据后，在代码中实例化此对象：

$data = getStuffFromAPI();
$image = new MyImage($data);
return $image->getImageThumbnails();

如何将多维数组转换为对象：（Singleton方法）

class ArrayConvertor {

    private static $obj;

    private __construct(){}
    private __clone(){}

    public static function convertToObject($array = []) {
        self::$obj = is_array($array) ? (object) array_map("self::convertToObject",$array) : $array;
        return self::$obj;
    }

    public static function getImageThumbnails() {  // assuming specific array structure
        $thumbs = null;
        if (is_object(self::$obj)){
            $thumbs = self::$obj->data->itemdetails->attributes->images->thumbnails;
        }
        return $thumbs;
    }
}

$obj = ArrayConvertor::convertToObject($arr);

var_dump(ArrayConvertor::getImageThumbnails());
