问题描述
我正在使用ISO 3166-1-alpha 2代码传递给应用程序以检索本地供稿，例如/feeds/us在美国.我有一个switch语句，该语句基于该country_code提供供稿.
I'm using ISO 3166-1-alpha 2 codes to pass to an application to retrieve a localised feed e.g. /feeds/us for the USA. I have a switch statement which serves a feed based on that country_code.
有没有一种方法可以将两位数字代码转换为语言代码，例如en_US?我想知道是否有标准的/函数/库在PHP中执行此操作，或者是否需要构建自己的数组?
Is there a way to convert that two digit code to the language code e.g. en_US ? I'm wondering if there is a standard / function / library for doing this in PHP or whether I need to build my own array?
推荐答案
正如其他人指出的那样，由于许多国家/地区存在多种语言，因此没有内置功能.因此，不幸的是，我无法将您指向执行此操作的库，但是我确实继续编写了一个可以满足您需要的小函数.
As other have pointed out, there is no built-in function as this likely due to the reality of many countries having multiple languages. So unfortunately, I can't point you to a library that does this, but I did go ahead and write a little function which does what you want.
有两个警告，一个是如果不提供语言，它将选择列表中的第一个语言环境.为了解决这个问题，您必须在函数调用周围添加一些逻辑，以为其提供适当的语言.另一个是它需要安装php5-intl.
There are two caveats, one being if it isn't provided a language it will just pick the first locale in the list. To get around this, you'd have to put some logic around the function call to provide it with the appropriate language. The other is that it needs to have php5-intl installed.
