有人知道怎么做吗？
我将下面的代码存储在一个变量中，并希望以不同的方式进行响应，例如：
- 按国家划分的价值总和
- 按城市划分的价值总和
- 各州价值总和
类似于：
国家a:220
国家b:80
country-c:70
国家a:220
状态b:80
state-c:70
城市a:220
城市b:80
city-c:70
stdClass Object
(
[city-a, state-a, country-a] => 100
[city-a, state-a, country-a] => 120
[city-b, state-b, country-b] => 80
[city-c, state-c, country-c] => 70
)
感谢你的帮助！
如果您不理解代码或需要其他函数的帮助，请告诉我。我还缩短了json代码。您可能会在类中实现更多的函数，并为自己创建一个nive FB统计接口。
//编辑：好的，我为您创建了一个小的API接口。它包含一个include文件、一个用法示例和两个json文件示例。请按以下方式命名文件，并将它们全部放在同一文件夹中。
