用户友好的时区与PHP

我目前正试图找出让用户选择时区的最佳方式。我喜欢Google在您注册Google Analytics时执行此操作的方式。

Google方式

1）从下拉菜单中选择国家/地区（这个很容易，人们习惯在默认的国家/地区列表中找到自己的国家/地区）

2）显示所选国家/地区中所有时区的第二个下拉列表。这使得选择时区变得非常快速和容易。特别是因为用户甚至不必关心该国家是否只有一个时区。

PHP方式

每个推荐（在搜索Stack溢出之后）都使用DateTimeZone lib。此输出不是用户友好的，因为很难找到您的时区。您甚至无法使用键盘，因为每个时区都有前缀为Europe / Africa / etc.

回到我的问题。是否有一个lib，其中包含针对其时区映射的所有国家/地区的列表？如果没有，是否有更简单的方法让用户选择时区？

有http://php.net/manual/en/datetimezone.listidentifiers.php;并且应该很容易从列表的每个元素中删除“continent /”。页面上的一个示例甚至在代码中有这个。

我找到了一个unicode文档，它将时区用于夏令时同样工作的国家/地区。此列表将选项数减少到100.我使用this list创建包含所有这些条目的MySQL表。

然后，您可以轻松地从中创建下拉列表。使用PHP函数date_default_timezone_set()和php_code将正确设置时区。

这是MySQL表结构。
