result is error, how to fix it !
推荐答案
尝试一下:
echo $data->{'2G Network'};
问题不在于JSON，而是您尝试访问的对象属性中有一个空格.如果使用花括号{ }，则可以使用字符串来命名要获取/设置的属性.
The problem wasn't with JSON, but that you had a space in the object property you were trying to access. If you use curly braces { }, then you can use strings to name the property you want to get/set.
