php - 从邮政编码查找完整地址，解决方案是什么？

Question

基本上，我正在为我的网站制作申请表。我需要使用用户输入的邮政编码搜索完整地址，并希望提供该邮政编码的结果供他们选择。我知道需要某种数据库，但我正在努力寻找它，希望得到任何帮助。

Answer 1

在英国，您可以使用 192.com 从任何邮政编码获得完整地址。

他们在 192.com 上有一个完全免费的数据库

我不为他们或他们的任何广告商工作，但已将此网站用于许多数据输入应用程序。

根据您正在搜索的邮政编码格式化 URL。即

'a1 1aa' 将是 http://www.192.com/places/a/a1-1/a1-1aa

这将列出邮政编码中的所有地址。

这是我写的类(class)，希望对你有帮助:
