推荐答案

你根本不能信任IP地址：它们不仅可以改变（当用户在移动设备或笔记本电脑上移动时，或者当路由器被重置时），它们也被连接到单个路由器的所有用户共享 - 因此同一公司的所有员工都将共享相同的内容。 IP地址。



相反，使用cookie将跟踪ID或购物车存储在用户设备上 - 这样它与用户一起移动，他不会丢失它，他的购买不与其他用户共享。有很多信息可以通过Google提供示例代码： cookies php [ ^ ]

You can't trust IP addresses at all: not only can they change (as the user moves around on a mobile, or laptop, or when the router is reset), they are also shared by all users connected to a single router - so all employees at the same company would share the same IP address.

Instead, use cookies to store the tracking id or a shopping cart on the user device - that way it moves with the user, he doesn't lose it, and his purchases aren't shared with other users. There is loads of info complete with example code available via Google: cookies php[^]

简单：您使用 cookies [ ^ ]。
