有没有办法在 PHP 中获取可用语言环境的列表？

Is there a way to get the list of available locales in PHP?

提问by Benjamin

In Java, you can call Locale.getAvailableLocales()to get the list of available locales.

在 Java 中，您可以调用Locale.getAvailableLocales()以获取可用语言环境的列表。

I was expecting an equivalent from the PHP Localeclass, but could not find one.

我期待 PHP Locale类的等效项，但找不到。

Is there a way to get an array of all valid Locales?

有没有办法获得所有有效语言环境的数组？

Part of the confusion here is that PHP has two concepts called "locale" that are pretty much totally separate.

这里的部分混淆是 PHP 有两个几乎完全独立的概念，称为“语言环境”。

The first is the older one, which basically just uses the C locale features. That's what's behind setlocaleand the locale support in some of PHP's functions (like money_formatfor example). This is what other answers that mention running locale -aon the command line and using setlocaleare talking about.

第一个是较旧的，它基本上只使用 C 语言环境功能。这就是setlocale某些 PHP 函数（money_format例如）的背后和语言环境支持。这就是提到locale -a在命令行上运行和使用的其他答案setlocale所讨论的内容。

PHP's Localeclass and the other related functionality from the intlextensionis newer, and doesn't work the same way. Instead of using the libc locale stuff, it uses a library called ICU, which ships its own locale data. PHP doesprovide a method to determine which locales are supported by thissystem: ResourceBundle::getLocales. The documentation is a little wooly here, but you can call this as a static method and pass the blank string to use ICU's default resources, thus getting a list of the supported locales for intl:

PHP 的Locale类和来自intl扩展的其他相关功能更新，并且工作方式不同。它没有使用 libc 语言环境的东西，而是使用一个名为 ICU 的库，它提供自己的语言环境数据。PHP确实提供了一种方法来确定此系统支持哪些语言环境：ResourceBundle::getLocales。这里的文档有点混乱，但您可以将其称为静态方法并传递空白字符串以使用 ICU 的默认资源，从而获得支持的语言环境列表intl：

ResourceBundle::getLocales('');

回答by Benjamin

I don't think there is a built in functions for this. You need to ask the operating system which locales are installed.

我不认为有一个内置的功能。您需要询问操作系统安装了哪些语言环境。

For example, if you run on a unix system you will need to execute the command:

例如，如果您在 unix 系统上运行，则需要执行以下命令：

$ locale -a

On Windows you can try to call the setlocale()php function with all the items of the following list:

回答by Yevgeniy Afanasyev

you normally need only locales that compatible with UTF-8 to use it in html

您通常只需要与 UTF-8 兼容的语言环境即可在 html 中使用它

thus, the ResourceBundle is useless, but you still can call it like this

因此，ResourceBundle 是无用的，但你仍然可以这样称呼它

\ResourceBundle::getLocales('')

to be sure how useless it is.

确定它是多么无用。

So, you need to get a list of what supported by your Ubuntu (because Ubuntu is what you need)

因此，您需要获取 Ubuntu 支持的列表（因为 Ubuntu 是您所需要的）

    $string           = shell_exec("locale -a|grep .utf8");
    $array            = explode('.utf8' . "\n", $string);

you will get things like en_US, ru_RU, zh_CN- whatever you installed on your ubuntu. Now take one and use it like so

你会得到类似en_US, ru_RU, zh_CN- 无论你安装在你的 ubuntu 上的东西。现在拿一个并像这样使用它

$locale  = $array[0].'.UTF-8';
setlocale(LC_MONETARY, $locale);

but you can install more localeson your Ubuntu

但是你可以locales在你的 Ubuntu 上安装更多
