我正在尝试使用以下代码从youtube上获取视频：
$youtube_api_url = "https://www.googleapis.com/youtube/v3/search?key=".$new_key->api_key;
$youtube_api_url = $youtube_api_url."&order=relevance&type=video&maxResults=20&part=snippet&videoCategoryId=10&q=". urlencode(preg_replace('/[^a-zA-Z0-9_ %\[\]\.\(\)%&-]/s', '',$trackRecord->name));
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept: application/json'));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL,$youtube_api_url);
$result=curl_exec($ch);
$response = json_decode($result, true);
echo "<pre>"; print_r($response); die;
返回错误的结果数量如下：
