假设我使用YouTube API v3进行了简单的youtube搜索,并且得到了如下响应:

{
"kind": "youtube#searchListResponse",
"etag": "\"m2yskBQFythfE4irbTIeOgYYfBU/1MwZbx-vX21eNjUJjkUlNHKCIhI\"",

我想生成10个结果,但是只能从响应中选择1(一个)随机 [item]。如何才能随机化结果,并从整个响应中仅选择其中之一?

我见过 shuffle()array_rand()之类的函数,但是这些似乎并不是我需要的函数。

我还看到了如下片段:
$array = json_decode($JSON, true);
$random_entry = array_rand($array['items'], 1);
$json_data = json_encode($random_entry);

我已经尝试过了,但是它只返回“nextPageToken”或“kind”等字符串。

我想选择一个完整的 [item]并获取其所有相关的 [snippet]数据,例如channelId,标题,描述,缩略图等。

谁能指出我正确的方向?

最佳答案

试试这个

$array = json_decode($JSON, true);
$items = $array['items'];
$random_key = array_rand($items, 1);
$json_data = json_encode($items[$random_key]);

array_rand()返回数组键,而不是数组值。
