如果您正在使用php-intl来本地化您的应用程序，您可能希望使用ResourceBundle::getLocales()而不是您自己维护的静态列表。它还可以为您提供特定语言的locale。

<?php
print_r(ResourceBundle::getLocales(''));

/* Output might show
  * Array
  * (
  *    [0] => af
  *    [1] => af_NA
  *    [2] => af_ZA
  *    [3] => am
  *    [4] => am_ET
  *    [5] => ar
  *    [6] => ar_AE
  *    [7] => ar_BH
  *    [8] => ar_DZ
  *    [9] => ar_EG
  *    [10] => ar_IQ
  *  ...
  */
?>

我花了一整天的时间为我的公司整理这些信息，因为我们正在构建一个多语言平台。如果你发现任何问题，缺失的语言，或不正确的字符集，请编辑列表，以便将来更有用。下面是所有语言区域设置、名称和字符集的完整列表。

对于PHP数组，这里是链接https://github.com/jerryurenaa/language-list/blob/main/language-list-array.php

JSON的链接是https://github.com/jerryurenaa/language-list/blob/main/language-list-json.json

一段程序，列出有关语言代码、当地名称、货币iso代码和货币符号(如果有的话)的信息。 这是PHP版本中包含的本地数据。

<?php 

// get array of Locales codes included in PHP
$ARR_LANGS_PHP = ResourceBundle::getLocales('');

// prepa. an array for rendering
$LANGS = array();

foreach ($ARR_LANGS_PHP as $k => $v) {


        // currency ISO code if exist
        $currency_iso = NumberFormatter::create(
            $v,NumberFormatter::CURRENCY)
                ->getTextAttribute(NumberFormatter::CURRENCY_CODE);

        // if no currency ISO code -> 'XXX' is returned,  $currency_iso => ''
        $currency_iso = ( $currency_iso == 'XXX') ? '' : $currency_iso;

        // currency symbol if exist
        $currency_symbol = new NumberFormatter( $v, NumberFormatter::DECIMAL );
        $symbol = $currency_symbol->getSymbol(NumberFormatter::CURRENCY_SYMBOL);

        // if no symbol -> '¤' is returned,  $symbol => ''
        $symbol = ( $symbol == '¤' ) ? '' : $symbol;

        // return name of locale with details ex. Arabic (Tunisia)
        $descr_locale = Locale::getDisplayName($v, 'en');

        // add datas to lang array
        $LANGS[] = array(

                'code_min' => strtolower(substr($v, 0, 2)),
                // code -> ex. 'fr_FR'
                'code' => $v,
                // locale string in english for all
                'locale' => $descr_locale,
                // currency_iso -> ex. 'EUR'
                'currency_iso' => $currency_iso,
                // ex. €
                'symbol' => $symbol
        );
}

// var_dump( count($LANGS) ); // 732 langs
echo '<pre>';
print_r( $LANGS );
echo '</pre>';
exit;

?>

虽然公认的答案是相当完整的(我用自己的答案回答了类似的问题)，但我认为值得把所有支持的语言代码和变体以及编码放在一起，并为用户指向一个几乎在任何linux发行版中都存在的文件，以防他只是想要一个更快的答案，例如没有互联网。

语言环境的重要性在于，即使您在编写应用程序时不知道它们，您的环境/os也可以为所有已安装的语言环境提供格式化功能。我的Windows 7系统安装了211个地区(下面列出)，所以你不太可能针对这么多地区编写任何定制代码或翻译。

编辑:原始区域设置列表已被编辑，以添加以前未包含的其他区域设置。现在有228家上市了。

对于各种版本的英语来说，最重要的是数字和日期的格式。其他差异在您希望和能够满足特定变化的程度上是重要的。

从http://www.w3.org/International/articles/language-tags/

"Language tag syntax is defined by the IETF's BCP 47. BCP stands for 'Best Current Practice', and is a persistent name for a series of RFCs whose numbers change as they are updated. The latest RFC describing language tag syntax is RFC 5646, Tags for the Identification of Languages, and it obsoletes the older RFCs 4646, 3066 and 1766. You used to find subtags by consulting the lists of codes in various ISO standards, but now you can find all subtags in the IANA Language Subtag Registry."

我相信大多数语言环境感知应用程序(由专业人员编写)都遵守这个标准。它不只是某个人拼凑起来的东西，不同的人会有不同的解读。

我强烈建议您研究您的特定开发语言的国际化特性，因为如果不这样做，您很可能会重新发明轮子。
