Symfony 7.4 Intl Component

Overview

The Symfony Intl component provides access to localization data from the ICU library. It exposes static API classes for querying languages, scripts, countries, currencies, locales, and timezones with locale-aware name translation.

Quick Reference

ClassPurposeStandards
LanguagesLanguage names and codesISO 639-1 (alpha-2), ISO 639-2 (alpha-3)
ScriptsWriting system namesUnicode ISO 15924
CountriesCountry names and codesISO 3166-1 alpha-2, alpha-3, numeric
CurrenciesCurrency names, symbols, fractionsISO 4217
LocalesLocale namesICU locale identifiers
TimezonesTimezone names and offsetsIANA timezone database

All classes live in Symfony\Component\Intl namespace. All getNames() / getName() methods accept an optional locale parameter for translated output.

Common Patterns

php
use Symfony\Component\Intl\Countries;
use Symfony\Component\Intl\Languages;
use Symfony\Component\Intl\Currencies;
use Symfony\Component\Intl\Timezones;

// Get localized name
$name = Countries::getName('FR', 'de'); // 'Frankreich'

// List all entries (sorted by current locale)
$all = Languages::getNames();

// Validate a code
$valid = Currencies::exists('EUR'); // true

// Convert alpha-2 <-> alpha-3
$a3 = Countries::getAlpha3Code('FR'); // 'FRA'
$a2 = Countries::getAlpha2Code('FRA'); // 'FR'

Exception Handling

All lookup methods throw Symfony\Component\Intl\Exception\MissingResourceException for invalid codes.
