PHP无法从json编码读取对象

PHP无法从json编码读取对象,php,json,wordpress,Php,Json,Wordpress,我正在向youtube API发送请求以获取播放列表: // make GET request to the YouTube API $response = wp_remote_request( 'https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&playlistId='.$playlist_id.'&key='.$api_key.'&order=date&ma

我正在向youtube API发送请求以获取播放列表:

      // make GET request to the YouTube API
      $response = wp_remote_request( 'https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&playlistId='.$playlist_id.'&key='.$api_key.'&order=date&maxResults=25',
      array(
          'method'     => 'GET'
        )
      );
得到它后,我希望它是JSON格式的,因此我使用:

      $json = wp_remote_retrieve_body($response);
      $json_encoded = json_encode($json, true);
如果我是对的,那么现在应该是所提供值的JSON表示。因此,我得到:

{
    "kind": "youtube#playlistItemListResponse",
    "etag": "\"p4VTdlkQv3HQeTEaXevLePAydmU/Q2DmelXR9Ne48evrmJE9Q4yVvpU\"",
    "nextPageToken": "CAoQAE",
    "pageInfo": {
        "totalResults": 36,
        "resultsPerPage": 25
    },
    "items": [ ...
我只想储存这些物品。人们会认为我现在可以通过以下方式访问它们:

$json_encoded['items'];
然后将其存储到WordPress数据库中,如下所示:

      // if we have any items update the db with those results
      if ( isset ( $json_encoded['items'] )) {
        $videos['json'] = $json_encoded['items'];
        update_option( 'wpc_ylp_videos', $videos );
      }

很不幸,我得到了以下错误:

Warning: Illegal string offset 'items' in /Users/tobias/Sites/videos.dev.cc/wp-content/plugins/videos/includes/videos.php on line 61
"


我肯定我做错了什么事,但我不能对此束手无策。如何访问items对象?我对json_encode的使用正确吗?

对于那些不阅读评论的人;答案是使用json_解码而不是json_编码

json_encode转换为字符串


json_encode转换为字符串。我相信你正在寻找json_decode Ty Bailey,谢谢,这正是问题所在!哦,天哪。
