無法訪問JSON對象在PHP

我一直在試圖訪問以下數組中的「視頻ID」 JSON對象：無法訪問JSON對象在PHP

{ 
"kind": "youtube#searchListResponse", 
"etag": "\"m2yskBQFythfE4irbTIeOgYYfBU/652q8gXfNeBDSoSQrv8VCrAv0Ho\"", 
"nextPageToken": "CAUQAA", 
"regionCode": "AU", 
"pageInfo": { 
    "totalResults": 25, 
    "resultsPerPage": 5 
}, 
"items": [ 
    { 
    "kind": "youtube#searchResult", 
    "etag": "\"m2yskBQFythfE4irbTIeOgYYfBU/31YuvB6enDzigibEfdgUq4-ZYc0\"", 
    "id": { 
    "kind": "youtube#video", 
    "videoId": "Ldx1nwBd4AY" 
    }, 
    "snippet": { 
    "publishedAt": "2017-04-14T21:00:00.000Z", 
    "channelId": "UC-z95jtL6-oDyFueQPoZLfQ", 
    "title": "HOW TO PLAY NINTENDO DS GAMES ON iPHONE iOS 10 FOR FREE (NDS4iOS) - NDS4IOS Tutorial - Tech Scout", 
    "description": "LIKE THE VIDEO + TURN ON CHANNEL NOTIFICATIONS! HOW TO PLAY NINTENDO DS GAMES ON iPHONE iOS 10 FOR FREE (NDS4iOS) - NDS4IOS ...", 
    "thumbnails": { 
    "default": { 
     "url": "https://i.ytimg.com/vi/Ldx1nwBd4AY/default.jpg", 
     "width": 120, 
     "height": 90 
    }, 
    "medium": { 
     "url": "https://i.ytimg.com/vi/Ldx1nwBd4AY/mqdefault.jpg", 
     "width": 320, 
     "height": 180 
    }, 
    "high": { 
     "url": "https://i.ytimg.com/vi/Ldx1nwBd4AY/hqdefault.jpg", 
     "width": 480, 
     "height": 360 
    } 
    }, 
    "channelTitle": "Tech Scout", 
    "liveBroadcastContent": "none" 
    } 
    },

它從那裏繼續，但我一直在試圖訪問「視頻ID」使用下面的代碼對象：

$youtubeurl = "https://www.googleapis.com/youtube/v3/search?order=date&part=snippet&channelId=" . $channelid . "&key=" . $api; 
$youtubeinfo = file_get_contents($youtubeurl); 
$youtubeencoded = json_decode($youtubeinfo, true); 
$youtubevideoid = $youtubeencoded["data"]["items"][0]["videoID"]; 
echo $youtubevideoid;

我沒有與JSON太多的經驗，所以我剛剛在第4行的代碼（我認爲這是問題）從堆棧溢出的另一個問題。

你可以做' print_r（$ youtubeencoded）'查看解析的php數組結構 –

您的JSON中沒有節點data。您還錯過了節點id。此外，它videoId而不是videoID：

$youtubevideoid = $youtubeencoded["items"][0]["id"]["videoId"];

非常感謝！完美工作！ – Hydrone

嘗試

$youtubevideoid = $youtubeencoded["items"][0]["id"]["videoId"];

謝謝，但那沒有奏效。我會繼續玩它，並希望我找到有效的工作 – Hydrone

您的JSON文件wrong.it會像

{ 
    "kind": "youtube#searchListResponse", 
    "etag": "\"m2yskBQFythfE4irbTIeOgYYfBU/652q8gXfNeBDSoSQrv8VCrAv0Ho\"", 
    "nextPageToken": "CAUQAA", 
    "regionCode": "AU", 
    "pageInfo": { 
     "totalResults": 25, 
     "resultsPerPage": 5 
    }, 
    "items": [ 
    { 
     "kind": "youtube#searchResult", 
      "etag": "\"m2yskBQFythfE4irbTIeOgYYfBU/31YuvB6enDzigibEfdgUq4-ZYc0\"", 
     "id": { 
      "kind": "youtube#video", 
      "videoId": "Ldx1nwBd4AY" 
      }, 
      "snippet": { 
       "publishedAt": "2017-04-14T21:00:00.000Z", 
       "channelId": "UC-z95jtL6-oDyFueQPoZLfQ", 
       "title": "HOW TO PLAY NINTENDO DS GAMES ON iPHONE iOS 10 FOR FREE (NDS4iOS) - NDS4IOS Tutorial - Tech Scout", 
      "description": "LIKE THE VIDEO + TURN ON CHANNEL NOTIFICATIONS! HOW TO PLAY NINTENDO DS GAMES ON iPHONE iOS 10 FOR FREE (NDS4iOS) - NDS4IOS ...", 
      "thumbnails": { 
       "url": "https://i.ytimg.com/vi/Ldx1nwBd4AY/default.jpg", 
       "width": 120, 
       "height": 90 
    }, 
      "medium": { 
      "url": "https://i.ytimg.com/vi/Ldx1nwBd4AY/mqdefault.jpg", 
      "width": 320, 
      "height": 180 
      }, 
      "high": { 
      "url": "https://i.ytimg.com/vi/Ldx1nwBd4AY/hqdefault.jpg", 
       "width": 480, 
       "height": 360 
      } 
     }, 
     "channelTitle": "Tech Scout", 
     "liveBroadcastContent": "none" 
     } 
    ] 
}

然後你就可以使用此代碼

$data = json_decode($youtubejson,true); 
echo $data["kind"];
