php – foreach ruft das stdClass-Objekt ab

Das Folgende sind die erhaltenen grafischen NewsJSON-Daten. Wie erhält foreach Werte wie Titel, Autor, Digest usw.?

stdClass Object
(
    [item] => Array
        (
            [0] => stdClass Object
                (

    个人建议最好将json字符串转换成数组而不是对象,这样便于后续操作,也便于阅读。

    mixed json_decode ( string $json [, bool $assoc = false [, int $depth = 512 [, int $options = 0 ]]] )

    assoc 当该参数为 TRUE 时,将返回 array 而非 object 。
    试着将json_decode()第二个参数置为true。

    假设上面的对象名为obj

    $data = array();
    foreach ($obj->item as $item) {
        $data[] = $item->content->new_item[0];
    }
    var_dump($data);

         $object = (object) [
            'item' => [
                ['content' => [
                    'news_item' => [
                        'title'  => '标题1',
                        'author' => '作者1'
                        ]
                    ]
                ],
                ['content' => [
                    'news_item' => [
                        'title'  => '标题2',
                        'author' => '作者2'
                        ]
                    ]
                ]]
                
          ];
         
        $result = new stdClass();
        foreach($object->item as $val) {
            $result->title[] = $val['content']['news_item']['title'];
        }
        
        var_dump($result);die;

    好好理解@windfly说的,
    访问stdClass Object属性, 用:

    $obj->title;

    访问数组属性用:

    $obj['title'];

    显然你取不到, 是用 $obj['title'] 这样的写法写的
