如何在PHP中跟踪用户的位置/区域 [英] How to track users location / region in PHP

问题描述

我试图让用户浏览网站的国家/地区，以便我可以确定在网站上显示的货币。我尝试过使用可用的GET脚本： http://api.hostip.info ，但他们只是在返回XX时我测试它。

如果有人知道任何更好的方法，请分享。

谢谢。

解决方案

试试这些： b -country.webhosting.info/rel =nofollow> http://ip-to-country.webhosting.info/

http://www.ip2location.com/

两者都是IP地址到国家/地区数据库，它允许您查找给定IP地址的来源国家。

但是，重要的是要注意这些数据库不是100 ％准确。他们是一个很好的指导，但由于各种原因你会得到错误的结果。

• 很多人使用代理来绕过国家/特定块和过滤器。


• 许多IP范围分配给地理分布广泛的公司;你只会得到他们所在的国家，而不是真正的机器所在的国家（这通常是跟踪AOL用户的一个大问题，因为他们都显然居住在弗吉尼亚州）


• IP范围的控制有时会在国家/地区间传输，因此您可能会得到错误结果（特别是对于较小/连接不良的国家/地区）。
  

使数据库保持最新将缓解其中的一些问题，但不会完全解决它们（特别是代理问题），所以您应该始终考虑到会得到错误结果的事实。 / p>

I'm trying to get the country from which the user is browsing the website so I can work out what currency to show on the website. I have tried using the GET scripts available from: http://api.hostip.info but they just return XX when I test it.

If anyone knows any better methods please share.

Thanks.

解决方案

Try these:

http://ip-to-country.webhosting.info/

http://www.ip2location.com/

Both are IP address-to-country databases, which allow you to look up the country of origin of a given IP address.

However it's important to note that these databases are not 100% accurate. They're a good guide, but you will get false results for a variety of reasons.

• Many people use proxying to get around country-specific blocks and filters.
• Many IP ranges are assigned to companies with large geographic spread; you'll just get the country where they're based, not where the actual machine is (this always used to be a big problem for tracking AOL users, because they were all apparently living in Virginia)
• Control of IP ranges are sometimes transferred between countries, so you may get false results from that (especially for smaller/less well-connected countries)

Keeping your database up-to-date will mitigate some of these issues, but won't resolve them entirely (especially the proxying issue), so you should always allow for the fact that you will get false results.
