从嵌套的json响应中获取价值

Question

这是我要获取用户ID值的json响应。

我看到了类似的主题，但并没有帮助我。

这是我如何实现的代码：

$tweets3 = $connection->get("https://api.twitter.com/1.1/statuses/home_timeline.json?include_entities=true&trim_user=".$userid."");
        foreach ($tweets3 as $item)
        {
                 echo $item->text;
                echo "<br/>";
                $tweet = $item->text;
                $userid = $item->user; // How to get user id here?
        }

更新的代码

$tweets3 = $connection->get("https://api.twitter.com/1.1/statuses/home_timeline.json?include_entities=true&trim_user=".$userid."");
        $data = json_decode($tweets3,true);
         print_r($data);
        foreach($data as $key=>$val){
                 echo "--------------------------------<br />";
                 echo "Tweet : ".$val["text"];
                 echo "<br />";
                 echo "User : ".$val["user"]["name"];
                 echo "<br />--------------------------------<br />";
        }

但这没有任何输出。

Answer 1

你可以做

$tweets3 = $connection->get("https://api.twitter.com/1.1/statuses/home_timeline.json?include_entities=true&trim_user=".$userid."");

$data = json_decode($tweets3,true);

现在$data将是一个数组，您可以遍历并获取值

显示项目更新

foreach($data as $key=>$val){
 echo "--------------------------------<br />";
 echo "Tweet : ".$val["text"];
 echo "<br />";
 echo "User : ".$val["user"]["name"];
 echo "<br />--------------------------------<br />";

}

在上面我只显示了tweet文本和用户名，您可以在循环之前使用print_r($data)并查看不同的元素名称，并且可以在循环内显示。
