我有一个JSON文件,我正在努力获取数据。 这是JSON。 p>

code> pre>
我正在使用 p将其转换为数组 >
$ data = json_decode($ jsondata,true);
code> pre>
然后我可以通过以下方式提取数据: p >
$ operatingRevenue = $ data ['data'] [0] ['value'];
$ totalrevenue = $ data ['data'] [1] ['value'] ;
code> pre>
等,但是,我希望使用标记名称而不仅仅是订单,以防订单在JSON中发生变化。 类似 p>
$ operatingRevenue = $ data ['data'] ['operatingRevenue'];
code> pre>
