【问题描述】：
从 Google Maps API 获取地点详细信息时，我无法从返回的 JSON 中检索值。这是我要解析的特定 JSON：

我正在尝试特别从 name 和 formatted_address 键中检索数据。
我已经尝试了以下方法（例如上面的 json 文件被命名为 practice.json）：
$jsondata = file_get_contents("practice.json");
$fileDecode = json_decode($jsondata);
echo $fileDecode->result->name;
但我无法获得任何输出。非常感谢任何帮助！
编辑：这是直接取自 Google Maps API 的第二个 json，也无法从以下位置检索数据：

【问题讨论】：
-
请贴一些代码
-
使用
json_decode($json, true)并读取数组 -
@OscarZarrus 我发布了一些代码。我已经完成了许多 json 解码示例，我知道这似乎微不足道，但由于某种原因，我无法使用我发布的特定 json 检索数据。
-
@MASIDDIQUI 我已经尝试过了，也尝试将它作为我上面指定的对象访问，但我无法检索数据。
-
您的 json 的 json_encode 返回 NULL，因此您的 json 数据有一些错误
