The CLDR extension contains local language names for different languages, countries, currencies, and time units extracted from CLDR data. See translatewiki:CLDR for information.

• Download and move the extracted cldr folder to your extensions/ directory.
  Developers and code contributors should install the extension from Git instead, using:

  cdextensions/
  gitclonehttps://gerrit.wikimedia.org/r/mediawiki/extensions/cldr
  

• Add the following code at the bottom of your LocalSettings.php file:

  wfLoadExtension( 'cldr' );
  

• 👁 Yes
  Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

If you download from git, change the file from CLDR to cldr.

The CLDR extension comes with data pre-populated in the language files, but if you want to get the latest data from the Unicode Consortium, you'll need to download it from the CLDR site and then run a rebuild script.

Download newest data from CLDR site:

http://www.unicode.org/cldr/repository_access.html

Example (from within the cldr directory):

wgethttps://www.unicode.org/Public/cldr/latest/core.zip
unzipcore.zip-dcore
phprebuild.php

CLDR defines the class LanguageNames which has a static method, getNames(). LanguageNames::getNames accepts three parameters:

1. code – the ISO 639 (see Manual:Language#Language code for details) code of the preferred language to return the list in
2. fbMethod – fallback method, it should be set to one of the following:
   • LanguageNames::FALLBACK_NATIVE – Missing entries fallback to the native name (default)
   • LanguageNames::FALLBACK_NORMAL – Missing entries fallback through the fallback chain
3. list – which languages to return. Should be set to one of the following:
   • LanguageNames::LIST_MW_SUPPORTED – Only languages that have localization in MediaWiki
   • LanguageNames::LIST_MW – All languages that are in Names.php (default)
   • LanguageNames::LIST_MW_AND_CLDR – All languages that are either in MediaWiki or in CLDR

The language names are best access with MediaWiki core functions:

// Japanisch
$name = Language::fetchLanguageName( 'ja', 'de', 'all' );

CLDR defines the class CountryNames which has a static method, getNames(). CountryNames::getNames accepts one parameter:

1. code - the ISO 639 code of the preferred language to return the list in

The following example sets a variable to the list of all countries in CLDR in French.

if ( is_callable( array( 'CountryNames', 'getNames' ) ) ) {
 $countries = CountryNames::getNames( 'fr' );
}
