获取PHP的官方美国时区? [英] Get the official American time zone in PHP?

问题描述

我的帐户已存储在数据库中，并且每个帐户的状态都在文件中，我希望从那里将每个帐户链接到基于该帐户状态的时区.

I have account stored in my database and I have each account state on file, from there I want to link each account to a timezone based on the account state.

因此，如果帐户的州为加利福尼亚州，则时区将为"America/Los_Angeles"

so if the account's state is California then the timezone will be "America/Los_Angeles"

更多，我想细分此页面上提供的时区 http: //php.net/manual/en/timezones.america.php 由 大西洋 东 中央 山 太平洋地区 阿拉斯加州 夏威夷-阿留申语

More, I want to break down the time zone that is provided at this page http://php.net/manual/en/timezones.america.php by Atlantic Eastern Central Mountain Pacific Alaska Hawaii - Aleutian

现在，我将能够基于7个时区对我的数据进行排序，而且我可以将我的所有帐户都链接到一个时区，以便确定其时区.

Now I will be able to sort my data based on 7 time zones and also I can have all my account linked to a timezone so I can determine their time zone.

所以我的问题 1)如何确定哪个状态链接到哪个时区. (例如:加利福尼亚=美国/洛杉矶")

So My question 1) How can I figure out what state is linked to what timezone. (example: California = "America/Los_Angeles")

2)哪个时区链接到哪个时区类别. (例如:加利福尼亚=太平洋)

2) Which timezone are linked to what timezone category. (example: California = Pacific)

推荐答案

您还没有想到.

美国许多州有多个时区.例如，南达科他州既有山区时区，又有中部时区.

Many US states have multiple time zones. For example, South Dakota has both Mountain and Central time zones.

如果您希望将位置解析为时区，则将需要更精细的位置.理想情况下是经度和纬度.如果您没有邮政编码，则可以近似邮政编码的质心纬度，然后将其用于将其解析为时区的多种服务或数据库中的任何一种.但是请务必小心，并非所有邮政编码都代表实际位置，并且邮政编码经常更改.

If you desire to resolve a location to a time zone, you will need a much more granular location. Ideally, a latitude and longitude. If you don't have one, you can approximate the centroid lat/lon of a zip code, and then use that against any of many various services or databases that will resolve that to a time zone. But be very careful, not all zip codes represent physical locations, and zip codes change frequently.
