【问题描述】：
在我的页面上，我有许多注册用户，每个用户都有一个邮政编码存储在我表中的行中。
我想知道它是否可能，如果可能，如何获取我的网站访问者的邮政编码，然后向他们显示最近的用户正在访问我表中的数据？

【讨论】：
您需要为每条记录填充纬度/经度，然后使用谷歌地图查找最近的用户，我相信以下链接会对您有所帮助。
Get latitude and longitude based on location name with Google Autocomplete API
【讨论】：
您可以使用 HTML 5 Geolocation要求他们向您提供他们的位置。然后你可以根据他们的经度/纬度查找最近的邮政编码。
您可以在此处获取北美的免费邮政/邮编数据（长/纬度）：
【讨论】：
如果您可以准确地确定访问用户的坐标，您可以使用google reverse geocoding API 将坐标转换为地址并使用该地址的邮政编码。
但确定访问者的准确坐标可能很困难。您必须依赖像 http://www.maxmind.com/app/php 这样的 GeoLocation api 或执行 HTML5 GeoLocation API。
