我认为没有内置功能。您需要询问操作系统安装了哪些语言环境。
例如，如果在unix系统上运行，则需要执行命令：
$ locale -a
答案 1 :(得分：12)
这里令人困惑的部分原因是PHP有两个名为“locale”的概念，几乎完全是分开的。
第一个是旧的，它基本上只使用C语言环境功能。这就是setlocale背后的内容以及PHP的一些函数中的语言环境支持（例如money_format）。这就是提及在命令行上运行locale -a并使用setlocale的其他答案。
PHP的Locale类和other related functionality from the intl extension更新，并且工作方式不同。它不使用libc语言环境，而是使用一个名为ICU的库，它提供自己的语言环境数据。 PHP 提供了一种方法来确定此系统支持哪些语言环境：ResourceBundle::getLocales。这里的文档有点毛茸茸，但您可以将其称为静态方法并传递空字符串以使用ICU的默认资源，从而获得intl支持的语言环境列表：
ResourceBundle::getLocales('');

这可能与OP略有不同，但是我觉得这是一个足够常见的用例，在这里可以提及。如果您需要列表语言代码 as defined by ICU，而不是列表 locales ，怎么办？
基于ResourceBundle::getLocales('');的解决方案将为您提供语言环境。然后，您需要将它们映射到语言代码。但是即使这样，语言列表仍然不完整。
以下是如何正确执行的比较：
<?php
function getListFromLocales(): array
{
return array_filter(ResourceBundle::getLocales(''), function ($value) {
return strpos($value, '_') === false;
});
}
function getListFromLanguages(): array
{
$resourceBundle = new ResourceBundle('en', 'ICUDATA-lang', false);
$languagesBundle = $resourceBundle['Languages'];
$languages = [];
foreach ($languagesBundle as $languageCode => $languageName) {
$languages[] = $languageCode;
}
return $languages;
}
function languageForEndUser($language): string
{
return Locale::getDisplayLanguage($language, $language) . ' (' . Locale::getDisplayLanguage($language) . ')';
}
$list1 = getListFromLocales();
$list2 = getListFromLanguages();
echo 'languages in list1: ' . count($list1) . PHP_EOL;
echo 'languages in list2: ' . count($list2) . PHP_EOL;
echo 'languages that exists in list1, but not in list2: ' . count(array_diff($list1, $list2)) . PHP_EOL;
echo 'languages that exists in list2, but not in list1: ' . count(array_diff($list2, $list1)) . PHP_EOL;
Locale::setDefault('fr'); // Assume end-user speaks french
echo 'examples of language for end-user: ' . PHP_EOL;
echo ' - ' . languageForEndUser('en') . PHP_EOL;
echo ' - ' . languageForEndUser('fr') . PHP_EOL;
echo ' - ' . languageForEndUser('ko') . PHP_EOL;
这将输出类似于：
languages in list1: 204
languages in list2: 620
languages that exists in list1, but not in list2: 0
languages that exists in list2, but not in list1: 416
examples of language for end-user:
- English (anglais)
- français (français)
- 한국어 (coréen)
在这里我们可以看到正确的方法产生了大约400（！）种语言。

您通常只需要与UTF-8兼容的语言环境才能在html中使用
因此，ResourceBundle没用，但是您仍然可以这样称呼它
String确保它毫无用处。
因此，您需要获取Ubuntu支持的列表（因为您需要Ubuntu）
\ResourceBundle::getLocales('')
您将获得 $string = shell_exec("locale -a|grep .utf8");
$array = explode('.utf8' . "\n", $string);
，en_US，ru_RU之类的东西-无论您在Ubuntu上安装了什么。现在拿一个像这样使用它
zh_CN但是您可以在Ubuntu上安装更多$locale = $array[0].'.UTF-8';
setlocale(LC_MONETARY, $locale);
答案 6 :(得分：-1)
system("locale -a|grep XX");其中XX是语言代码，即。 system("locale -a|grep de");
