このjson形式から最初のvideoId、タイトル、説明、サムネイルの高価値を取得する方法は？

Question

このjson形式から最初のvideoId、title、description、thumbnailsの値を高くするにはどうすればよいですか？

私はこのコード

<?PHP 
$curl_value = curl_init('https://www.googleapis.com/youtube/v3/search?part=snippet&maxResults=3&search_query=test&key=youtube_api_key'); 
curl_setopt($curl_value, CURLOPT_RETURNTRANSFER, true); 
$json_exec = curl_exec($curl_value); 
$result_json = json_decode($json_exec); 
$video_id = $result_json->items[0]->videoId; 
$title = $result_json->items[0]->snippet->title; 
$description = $result_json->items[0]->snippet->description; 
$thumbnails = $result_json->items[0]->snippet->thumbnails->high; 

echo $video_id; 
echo $title; 
echo $description; 
echo $thumbnails; 
?> 

これを使用しています。

しかし、データを取得できません。どのようにすればいいですか？私は

VIDEOID = iKzRIweSBLA

タイトルを取得したい。このケースでは

= Ed Sheeran - Perfect [Official Lyric Video]

これは、JSON結果

です

Answer 1

titleとdescriptionは既に動作しています。 video_idとthumbnailsは非常に近いです。

$video_id = $result_json->items[0]->id->videoId; 
$title  = $result_json->items[0]->snippet->title; 
$description = $result_json->items[0]->snippet->description; 
$thumbnails = $result_json->items[0]->snippet->thumbnails->high->url;
