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.
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?
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.
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.
