【问题描述】：

我一直在做我的一个小项目，现在我想使用 tmdb_id 找到 imdb_id，因此我一直在尝试使用 API。 https://api.themoviedb.org/3/tv/67026?api_key=myapikey&append_to_response=external_ids

这会带来这样的结果

所以现在如果我只想从 external_ids 中获取 IMDb_ID，那么我应该在 php 中使用什么代码并将其存储在变量中。

非常感谢您。

【问题讨论】：

如果您能够在没有问题的情况下获得响应，只需使用json_decode，然后像往常一样将其视为对象/数组并将其分配到变量中

对不起，您在问 PHP - javascript 标签让我失望

可能应该删除javascript（和html）标签，也许用JSON替换它。

这可能与以下内容重复：***.com/questions/29308898/…

【参考方案1】：

使用 json_decode 方法将 JSON 视为 PHP 对象

$data = 'your JSON object';//raw data as string in $data
$decoded = json_decode($data);//decoded data as PHP object
echo $decoded->external_ids->imdb_id; //access any property you like

希望对你有帮助！！！
