Language and Script Names

The Languages class provides access to the name of all languages according to the ISO 639-1 alpha-2 list and the ISO 639-2 alpha-3 list:

1
2
3
4
5
6

use Symfony\Component\Intl\Languages;

\Locale::setDefault('en');

$languages = Languages::getNames();
// ('languageCode' => 'languageName')
// => ['ab' => 'Abkhazian', 'ace' => 'Achinese', ...]

$language = Languages::getName('fr');
// => 'French'

All methods accept the translation locale as the last, optional parameter, which defaults to the current default locale:

1
2
3
4
5

$languages = Languages::getNames('de');
// => ['ab' => 'Abchasisch', 'ace' => 'Aceh', ...]

$language = Languages::getName('fr', 'de');
// => 'Französisch'

If the given locale doesn't exist, the methods trigger a MissingResourceException. In addition to catching the exception, you can also check if a given language code is valid:

1

$isValidLanguage = Languages::exists($languageCode);

The Scripts class provides access to the optional four-letter script code that can follow the language code according to the Unicode ISO 15924 Registry (e.g. HANS in zh_HANS for simplified Chinese and HANT in zh_HANT for traditional Chinese):

use Symfony\Component\Intl\Scripts;

\Locale::setDefault('en');

$scripts = Scripts::getNames();
// ('scriptCode' => 'scriptName')
// => ['Adlm' => 'Adlam', 'Afak' => 'Afaka', ...]

$script = Scripts::getName('Hans');
// => 'Simplified'

All methods accept the translation locale as the last, optional parameter, which defaults to the current default locale:

5

$scripts = Scripts::getNames('de');
// => ['Adlm' => 'Adlam', 'Afak' => 'Afaka', ...]

$script = Scripts::getName('Hans', 'de');
// => 'Vereinfacht'

If the given script code doesn't exist, the methods trigger a MissingResourceException. In addition to catching the exception, you can also check if a given script code is valid:

1

$isValidScript = Scripts::exists($scriptCode);

Country Names

The Countries class provides access to the name of all countries according to the ISO 3166-1 alpha-2 list of officially recognized countries and territories:

use Symfony\Component\Intl\Countries;

\Locale::setDefault('en');

$countries = Countries::getNames();
// ('countryCode' => 'countryName')
// => ['AF' => 'Afghanistan', 'AX' => 'Åland Islands', ...]

$country = Countries::getName('GB');
// => 'United Kingdom'

All methods accept the translation locale as the last, optional parameter, which defaults to the current default locale:

1

3
4
5

$countries = Countries::getNames('de');
// => ['AF' => 'Afghanistan', 'EG' => 'Ägypten', ...]

$country = Countries::getName('GB', 'de');
// => 'Vereinigtes Königreich'

If the given country code doesn't exist, the methods trigger a MissingResourceException. In addition to catching the exception, you can also check if a given country code is valid:

1

$isValidCountry = Countries::exists($countryCode);

Locales

A locale is the combination of a language and a region. For example, "Chinese" is the language and zh_Hans_MO is the locale for "Chinese" (language) + "Simplified" (script) + "Macau SAR China" (region). The Locales class provides access to the name of all locales:

use Symfony\Component\Intl\Locales;

\Locale::setDefault('en');

$locales = Locales::getNames();
// ('localeCode' => 'localeName')
// => ['af' => 'Afrikaans', 'af_NA' => 'Afrikaans (Namibia)', ...]

$locale = Locales::getName('zh_Hans_MO');
// => 'Chinese (Simplified, Macau SAR China)'

All methods accept the translation locale as the last, optional parameter, which defaults to the current default locale:

1
2
3
4
5

$locales = Locales::getNames('de');
// => ['af' => 'Afrikaans', 'af_NA' => 'Afrikaans (Namibia)', ...]

$locale = Locales::getName('zh_Hans_MO', 'de');
// => 'Chinesisch (Vereinfacht, Sonderverwaltungsregion Macau)'

If the given locale code doesn't exist, the methods trigger a MissingResourceException. In addition to catching the exception, you can also check if a given locale code is valid:

1

$isValidLocale = Locales::exists($localeCode);

Currencies

The Currencies class provides access to the name of all currencies as well as some of their information (symbol, fraction digits, etc.):

1

7
8
9
10
11
12
13

use Symfony\Component\Intl\Currencies;

\Locale::setDefault('en');

$currencies = Currencies::getNames();
// ('currencyCode' => 'currencyName')
// => ['AFN' => 'Afghan Afghani', 'ALL' => 'Albanian Lek', ...]

$currency = Currencies::getName('INR');
// => 'Indian Rupee'

$symbol = Currencies::getSymbol('INR');
// => '₹'

$fractionDigits = Currencies::getFractionDigits('INR');
// => 2

$roundingIncrement = Currencies::getRoundingIncrement('INR');
// => 0

All methods (except for getFractionDigits() and getRoundingIncrement()) accept the translation locale as the last, optional parameter, which defaults to the current default locale:

1
2
3
4
5

$currencies = Currencies::getNames('de');
// => ['AFN' => 'Afghanischer Afghani', 'EGP' => 'Ägyptisches Pfund', ...]

$currency = Currencies::getName('INR', 'de');
// => 'Indische Rupie'

If the given currency code doesn't exist, the methods trigger a MissingResourceException. In addition to catching the exception, you can also check if a given currency code is valid:

1

$isValidCurrency = Currencies::exists($currencyCode);

Timezones

The Timezones class provides several utilities related to timezones. First, you can get the name and values of all timezones in all languages:

1
2
3
4
5
6
7
8
9
10

use Symfony\Component\Intl\Timezones;

\Locale::setDefault('en');

$timezones = Timezones::getNames();
// ('timezoneID' => 'timezoneValue')
// => ['America/Eirunepe' => 'Acre Time (Eirunepe)', 'America/Rio_Branco' => 'Acre Time (Rio Branco)', ...]

$timezone = Timezones::getName('Africa/Nairobi');
// => 'East Africa Time (Nairobi)'

All methods accept the translation locale as the last, optional parameter, which defaults to the current default locale:

1
2
3
4
5

$timezones = Timezones::getNames('de');
// => ['America/Eirunepe' => 'Acre-Zeit (Eirunepe)', 'America/Rio_Branco' => 'Acre-Zeit (Rio Branco)', ...]

$timezone = Timezones::getName('Africa/Nairobi', 'de');
// => 'Ostafrikanische Zeit (Nairobi)'

You can also get all the timezones that exist in a given country. The forCountryCode() method returns one or more timezone IDs, which you can translate into any locale with the getName() method shown earlier:

1
2
3

// unlike language codes, country codes are always uppercase (CL = Chile)
$timezones = Timezones::forCountryCode('CL');
// => ['America/Punta_Arenas', 'America/Santiago', 'Pacific/Easter']

The reverse lookup is also possible thanks to the getCountryCode() method, which returns the code of the country where the given timezone ID belongs to:

1
2

$countryCode = Timezones::getCountryCode('America/Vancouver')
// => $countryCode = 'CA' (CA = Canada)

The UTC/GMT time offsets of all timezones are provided by getRawOffset() (which returns an integer representing the offset in seconds) and getGmtOffset() (which returns a string representation of the offset to display it to users):

1
2
3
4
5
6
7

$offset = Timezones::getRawOffset('Etc/UTC');              // $offset = 0
$offset = Timezones::getRawOffset('America/Buenos_Aires'); // $offset = -10800
$offset = Timezones::getRawOffset('Asia/Katmandu');        // $offset = 20700

$offset = Timezones::getGmtOffset('Etc/UTC');              // $offset = 'GMT+00:00'
$offset = Timezones::getGmtOffset('America/Buenos_Aires'); // $offset = 'GMT-03:00'
$offset = Timezones::getGmtOffset('Asia/Katmandu');        // $offset = 'GMT+05:45'

The timezone offset can vary in time because of the daylight saving time (DST) practice. By default these methods use the time() PHP function to get the current timezone offset value, but you can pass a timestamp as their second arguments to get the offset at any given point in time:

1
2
3
4
5

// In 2019, the DST period in Madrid (Spain) went from March 31 to October 27
$offset = Timezones::getRawOffset('Europe/Madrid', strtotime('March 31, 2019'));   // $offset = 3600
$offset = Timezones::getRawOffset('Europe/Madrid', strtotime('April 1, 2019'));    // $offset = 7200
$offset = Timezones::getGmtOffset('Europe/Madrid', strtotime('October 27, 2019')); // $offset = 'GMT+02:00'
$offset = Timezones::getGmtOffset('Europe/Madrid', strtotime('October 28, 2019')); // $offset = 'GMT+01:00'

The string representation of the GMT offset can vary depending on the locale, so you can pass the locale as the third optional argument:

1
2

$offset = Timezones::getGmtOffset('Europe/Madrid', strtotime('October 28, 2019'), 'ar')); // $offset = 'غرينتش+01:00'
$offset = Timezones::getGmtOffset('Europe/Madrid', strtotime('October 28, 2019'), 'dz')); // $offset = 'ཇི་ཨེམ་ཏི་+01:00'

If the given timezone ID doesn't exist, the methods trigger a MissingResourceException. In addition to catching the exception, you can also check if a given timezone ID is valid:

1

$isValidTimezone = Timezones::exists($timezoneId);
