一个用php写的简易订阅整合
支持：合并订阅，零散节点，去重，以普通或base64格式返回

在同级目录新建 sub.txt 放置订阅，例如

https://sub.vip.sd/JPa6vvFgygVtNP2sGJ2r/download/nlmjj?target=V2Ray
https://fly.j-s.us.kg/api/v1/client/subscribe?token=3275fdb3e5ff32434a293ca8ca8fe9dc

在同级目录新建 scatter.txt 放置零散节点，例如

默认url格式，要以base64返回应增加 ?base64 后缀
clash配置应增加 ?clash 后缀
