我正在尝试从 Vimeo Api 中检索该字段的值，我已经尝试了此处提到的所有可能的解决方案。谁能告诉我如何分别从缩略图和 url 对象中检索缩略图和 url？

array(1) {
    [0]=>       
        stdClass Object (
            [allow_adds] => 1
            [embed_privacy] => anywhere
            [id] => 123456789
            [is_hd] => 0
            [is_transcoding] => 0
            [license] => 0
            [privacy] => anybody
            [title] => Soap Opera
            [description] => 
            [upload_date] => 2014-02-20 03:03:50
            [modified_date] => 2014-02-20 19:06:05
            [number_of_plays] => 1
            [number_of_likes] => 0
            [number_of_comments] => 0
            [width] => 600
            [height] => 480
            [duration] => 32
            [owner] => stdClass Object (
                [display_name] => blah
                [id] => 12345678
                [is_plus] => 0
                [is_pro] => 1
                [is_staff] => 0
                [profileurl] => http://vimeo.com/st
                [realname] => ST
                [username] => ST
                [videosurl] => http://vimeo.com/st/videos
                [portraits] => stdClass Object (
                    [portrait] => Array (
                        [0] => stdClass Object (
                            [height] => 30
                            [width] => 30
                            [_content] => http://b.vimeocdn.com/x.jpg
                        )

                        [1] => stdClass Object (
                            [height] => 75
                            [width] => 75
                            [_content] => http://b.vimeocdn.com/x.jpg
                        )

                        [2] => stdClass Object (
                            [height] => 100
                            [width] => 100
                            [_content] => http://b.vimeocdn.com/x.jpg
                        )

                        [3] => stdClass Object (
                            [height] => 300
                            [width] => 300
                            [_content] => http://b.vimeocdn.com/x.jpg
                        )

                    )

                )

            )

            [urls] => stdClass Object (
                [url] => Array (
                    [0] => stdClass Object (
                        [type] => video
                        [_content] => http://vimeo.com/0000
                    )
                )
            )

        [thumbnails] => stdClass Object (
            [thumbnail] => Array (
                [0] => stdClass Object (
                    [height] => 75
                    [width] => 100
                    [_content] => http://b.vimeocdn.com/x.jpg
                )
            )
        )
    )

我有一个数组 $vids ，它包含各种视频的元信息以及循环内的另一个调用，该循环获取第二个数组 $vidInfo 包含上面显示的数组对于每个条目。我可以像正常访问对象一样检索标题等。 但我无法再遍历上面的响应。

<?php 
     $vids = $videos->videos->video;    
         foreach ($vids as $vid){
             $id = $vid->id;
             $vidInfo = $vimeo->call('vimeo.videos.getInfo', array('video_id' => $id));
             $vidUrl = $vidInfo->video;  
             echo  $vid->title;
             echo '<br />';
             print_r($vidUrl->urls->url[0]->{'_content'});
             //echo '<pre>' . print_r($vidUrl) .  '</pre>'; 
         }
    ?>

非常感谢

最佳答案

考虑到你有:

    [urls] => stdClass Object
    (
        [url] => Array
            (
                [0] => stdClass Object
                    (
                        [type] => video
                        [_content] => http://vimeo.com/0000
                    )

            )

    )

访问对象是通过对象访问运算符 (->) 完成的，而访问数组是通过方括号 ([x]) 完成的。 所以在这种情况下，您最终会得到 urls->url[0]->_content。由于 urls 是一个对象，而 url 是一个数组，其第一个 ([0]) 索引包含另一个对象。

简而言之，回答您的完整原始问题: $object->urls->url[0]->_content 是网址 和 $object->thumbnails->thumbnail[0]->_content为缩略图
