Php 根据IP位置的半径显示不同的内容？

我需要根据用户的ip位置在主页上显示不同的电话号码。这将是一个动态的和不断变化的门店数量。因此，如果用户访问该站点，并且他们的ip地址位于我们其中一家店铺的50英里以内，则会显示该店铺编号。如果我们在他们所在地50英里内没有商店，将显示默认号码。当我们开一家新店时，我们会在Wordpress中的一个自定义字段中添加电话号码和城市（或zip，无论需要什么）。这些数据就是我需要用来进行地理定位的数据

我读过无数的文章，知道我需要连接到像max mind这样的数据库，但我不知道如何做半径部分。谁能给我指出正确的方向吗？一个插件或免费服务，可以让我大部分的方式呢

谢谢。

看看

需要做很多事情

浏览器会让用户知道您正在尝试检测他们的位置，并给用户一个拒绝地理定位尝试的选项。如果他们这样做，您需要有一个后备功能，例如搜索您的店铺或显示特定店铺的号码，例如总部

如果用户接受地理定位尝试，您可以根据大量计算（如的步骤3中提供的计算）计算其距离。对于工作示例，请查看哪个工作完美无瑕，并且在任何演示页面的搜索结果中都可以看到许多UI选项和工作半径检测。您还可以深入研究他的代码，看看他是如何计算半径的，或者他使用哪些第三方函数来计算半径的

如果您在wordpress中实现此功能，您可能需要为其编写一个简单的插件，并创建一个简单的短代码与之一起使用，或者将您的函数添加到functions.php文件中，不过最好编写一个插件，使您的工作井然有序，并且更易于以后的编辑/维护

我希望我的IP地址的解析地理位置像你建议的那样准确（使用公开可用的数据库；NSA可能有这样的数据），否则我真的应该开始更认真地研究TOR。你应该将php和word press标签添加到我看到的大多数网站，询问用户位置，我认为这是一个更好的主意，你在wordpress数据库中启用了PDO？？谢谢。我认为只有使用基于GPS的地理定位系统，才会出现地理定位提示。如果它只是基于IP，它也会这样做吗？我意识到它不如GPS准确…如果使用基于GPS的定位，则会始终出现提示，但我不确定是否会出现基于IP的定位。不过GPS的精确度肯定更好。谢谢你，这看起来很有希望。虽然附近的建议似乎是maxmind提供的通用位置。我必须弄清楚如何整合我自己的门店。
