根据 IP 位置的半径显示不同的内容 - Show different content based on radius of IP location?

我需要根据用户的IP位置在主页上显示不同的电话号码。它将用于动态和不断变化的商店位置数量。因此，如果用户访问该网站并且他们的 IP 位置距离我们的一家商店 50 英里以内，将显示该商店编号。如果我们在其位置 50 英里范围内没有商店，将显示默认编号。当我们开设新商店时，我们会将电话号码和城市（或邮政编码，无论需要什么）添加到 Wordpress 中的自定义字段中。这些数据是我需要用来进行地理定位的数据。

我已经阅读了无数的文章，并且知道我需要连接到像max mind这样的数据库，但是我不知道如何做半径部分。谁能指出我正确的方向？一个插件或免费服务，可以让我大部分时间到达那里？

谢谢。

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，并为用户提供拒绝地理位置尝试的选项。如果他们这样做，您需要有一个后备，例如搜索页面或显示特定商店的编号，例如总部。
如果用户接受地理位置尝试，则可以根据许多计算来计算其接近度，例如本教程的步骤 3 中提供的计算。有关工作示例，请查看 Bjorn 的商店定位器插件，该插件完美运行，并带有许多 UI 选项和在任何演示页面的搜索结果中可见的工作半径检测。您还可以深入研究他的代码，看看他是如何计算半径的，或者他使用了哪些第三方函数来计算半径。
如果你在wordpress中实现这一点，你可能需要为它编写一个简单的插件，并创建一个简单的简码与它一起使用，或者将你的函数添加到函数.php文件中，尽管最好编写一个插件并保持你的工作井井有条，因此以后更容易编辑/维护。

看看

echo var_export(unserialize(file_get_contents('http://www.geoplugin.net/php.gp?ip='.$_SERVER['REMOTE_ADDR'])));

输出
