CLDR

The CLDR package provides means to internationalize your application by leveraging the data and conventions defined by the Unicode Common Locale Data Repository (CLDR). It offers many helpful locale information and data (such as locale names for territories, languages, days…) as well as formatters for numbers, currencies, dates and times, units, sequences, lists…

Note

The package targets CLDR version 36.

Installation

composer require icanboogie/cldr

Repository

The CLDR is represented by a Repository instance, from which data is accessed. When required, data is retrieved through a provider. The web provider fetches data from the JSON distribution hosted on GitHub. In order to avoid hitting the web with every request, a collection of caches is used, each with its own strategy.

The following example demonstrates how a repository can be instantiated:

<?phpnamespaceICanBoogie\CLDR;
useICanBoogie\CLDR\Cache\CacheCollection;
useICanBoogie\CLDR\Cache\FileCache;
useICanBoogie\CLDR\Cache\RedisCache;
useICanBoogie\CLDR\Cache\RuntimeCache;
useICanBoogie\CLDR\Provider\CachedProvider;
useICanBoogie\CLDR\Provider\WebProvider;
/* @var \Redis $redis_client */$provider = newCachedProvider(
newWebProvider,
newCacheCollection([
newRunTimeCache,
newRedisCache($redis_client),
newFileCache("/path/to/storage")
])
);
$repository = newRepository($provider);

Accessing the repository

The repository can be accessed like a big array, but it also provides interfaces to the most important data such as locales, territories, numbers, currencies…

The following example demonstrates how the repository can be used to access locales and supplemental data:

<?php/* @var $repository \ICanBoogie\CLDR\Repository */$english_locale = $repository->locales['en'];
$french_locale = $repository->locales['fr'];
$repository->available_locales; // [ … 'en', …, 'fr', … ];$repository->is_locale_available('fr'); // true$repository->is_locale_available('fr-FR'); // false$supplemental = $repository->supplemental;
# reading the default calendarecho$supplemental['calendarPreferenceData']['001']; // gregorian

Locales

The data and conventions of a locale are represented by a Locale instance, which can be used as an array to access various raw data such as calendars, characters, currencies, delimiters, languages, territories and more.

<?php/* @var $repository \ICanBoogie\CLDR\Repository */$locale = $repository->locales['fr'];
echo$locale['characters']['auxiliary']; // [á å ä ã ā ē í ì ī ñ ó ò ö ø ú ǔ]echo$locale['delimiters']['quotationStart']; // «echo$locale['territories']['TF']; // Terres australes françaises

Locales provide a collection of calendars, and the calendar property is often used to obtain the default calendar of a locale.

<?php/* @var $repository \ICanBoogie\CLDR\Repository */$locale = $repository->locales['fr'];
echo$locale['ca-gregorian']['days']['format']['wide']['sun']; // dimanche# or using the calendar collectionecho$locale->calendars['gregorian']['days']['format']['wide']['sun']; // dimanche# or because 'gregorian' is the default calendar for this localeecho$locale->calendar['days']['format']['wide']['sun']; // dimanche

Localized objects

Locales are also often used to localize instances such as Currency, Territory, or even Locale. The method localize is used to localize instances. The method tries its best to find a suitable localizer, and it helps if the instance to localize implements Localizable, or if a ICanBoogie\CLDR\Localized<class_base_name> class is defined.

<?php/* @var $repository \ICanBoogie\CLDR\Repository */$datetime = new \DateTime;
$localized_datetime = $repository->locales['fr']->localize($datetime);
echoget_class($localized_datetime); // ICanBoogie\CLDR\LocalizedDateTime

Instances that can be localized usually implement the localize() method.

<?php/* @var $repository \ICanBoogie\CLDR\Repository */echo$repository->territories['FR']->localize('fr')->name; // France

Localized locales

A localized locale can be obtained with the localize() method, or the localize() method of the desired locale.

<?php/* @var $repository \ICanBoogie\CLDR\Repository */$locale = $repository->locales['fr'];
echo$locale->localize('fr')->name; // Français# orecho$repository->locales['fr']->localize($locale)->name; // Français

Context transforms

Several capitalization contexts can be distinguished for which different languages use different capitalization behavior for dates, date elements, names of languages/regions/currencies. The context_transform() method helps capitalizing these elements:

<?phpuseICanBoogie\CLDR\ContextTransforms;
/* @var $repository \ICanBoogie\CLDR\Repository */echo$repository->locales['fr']->context_transform(
"juin",
ContextTransforms::USAGE_MONTH_FORMAT_EXCEPT_NARROW,
ContextTransforms::TYPE_STAND_ALONE
);
// Juin

Calendars

Calendars are represented by a Calendar instance, they can be accessed as arrays, and also provide magic properties to rapidly access days, eras, months and quarters:

<?phpuseICanBoogie\CLDR\Calendar;
/* @var $repository \ICanBoogie\CLDR\Repository */$calendar = newCalendar($repository->locales['fr'], $repository->locales['fr']['ca-gregorian']);
# or$calendar = $repository->locales['fr']->calendars['gregorian'];
# or$calendar = $repository->locales['fr']->calendar; // because "gregorian" is the default calendar for this locale$calendar->standalone_abbreviated_days;
# or $calender['days']['stand-alone']['abbreviated'];$calendar->abbreviated_days;
# or $calender['days']['format']['abbreviated'];

This works with days, eras, months, quarters and the following widths: abbreviated, narrow, short, and wide. Here are some examples:

<?php/* @var $calendar \ICanBoogie\CLDR\Calendar */$calendar->standalone_abbreviated_eras;
$calendar->standalone_narrow_months;
$calendar->standalone_short_quarters;
$calendar->standalone_wide_days;
$calendar->abbreviated_days;
$calendar->narrow_months;
$calendar->short_days;
$calendar->wide_quarters;

Dates and times formatters

From a calendar you can obtain formatters for dates and times.

The following example demonstrates how the dates and times formatters can be accessed and used.

<?php/* @var $repository \ICanBoogie\CLDR\Repository */$datetime = '2018-11-24 20:12:22 UTC';
$calendar = $repository->locales['fr']->calendar;
echo$calendar['days']['format']['wide']['sun']; // dimancheecho$calendar->wide_days['sun']; // dimancheecho$calendar->format_datetime($datetime, 'full'); // samedi 24 novembre 2018 20:12:22 UTCecho$calendar->format_date($datetime, 'long'); // 24 novembre 2018echo$calendar->format_time($datetime, 'long'); // 20:12:22 UTC# orecho$calendar->datetime_formatter->format($datetime, 'full'); // samedi 24 novembre 2018 20:12:22 UTCecho$calendar->date_formatter->format($datetime, 'long'); // 24 novembre 2018echo$calendar->time_formatter->format($datetime, 'long'); // 20:12:22 UTC

Dates and Times

Calendars provide a formatter for dates and times. A width, a skeleton or a pattern can be used for the formatting. The datetime can be specified as an Unix timestamp, a string or a DateTime instance.

<?phpuseICanBoogie\CLDR\DateTimeFormatter;
/* @var $repository \ICanBoogie\CLDR\Repository */$formatter = newDateTimeFormatter($repository->locales['en']->calendar);
# or$formatter = $repository->locales['en']->calendar->datetime_formatter;
$datetime = '2013-11-02 22:23:45 UTC';
echo$formatter($datetime, "MMM d, y"); // November 2, 2013echo$formatter($datetime, "MMM d, y 'at' hh:mm:ss a"); // November 2, 2013 at 10:23:45 PMecho$formatter($datetime, $formatter::WIDTH_FULL); // Saturday, November 2, 2013 at 10:23:45 PM UTCecho$formatter($datetime, $formatter::WIDTH_LONG); // November 2, 2013 at 10:23:45 PM UTCecho$formatter($datetime, $formatter::WIDTH_MEDIUM); // Nov 2, 2013, 10:23:45 PMecho$formatter($datetime, $formatter::WIDTH_SHORT); // 11/2/13, 10:23 PMecho$formatter($datetime, ':Ehm'); // Sat 10:23 PM

Date formatter

Calendars provide a formatter for dates. A width or a pattern is used for the formatting.

<?phpuseICanBoogie\CLDR\DateFormatter;
/* @var $repository \ICanBoogie\CLDR\Repository */$formatter = newDateFormatter($repository->locales['en']->calendar);
# or$formatter = $repository->locales['en']->calendar->date_formatter;
$datetime = '2013-11-05 21:22:23';
echo$formatter($datetime, $formatter::WIDTH_FULL); // Tuesday, November 5, 2013echo$formatter($datetime, $formatter::WIDTH_LONG); // November 5, 2013echo$formatter($datetime, $formatter::WIDTH_MEDIUM); // Nov 5, 2013echo$formatter($datetime, $formatter::WIDTH_SHORT); // 11/5/13

Time formatter

Calendars provide a formatter for times. A width or a pattern is used for the formatting.

<?phpuseICanBoogie\CLDR\TimeFormatter;
/* @var $repository \ICanBoogie\CLDR\Repository */$formatter = newTimeFormatter($repository->locales['en']->calendar);
# or$formatter = $repository->locales['en']->calendar->time_formatter;
$datetime = '2013-11-05 21:22:23 UTC';
echo$formatter($datetime, $formatter::WIDTH_FULL); // 9:22:23 PM UTCecho$formatter($datetime, $formatter::WIDTH_LONG); // 9:22:23 PM UTCecho$formatter($datetime, $formatter::WIDTH_MEDIUM); // 9:22:23 PMecho$formatter($datetime, $formatter::WIDTH_SHORT); // 9:22 PM

Localized DateTime

DateTime can be localized by wrapping them inside a LocalizedDateTime instance, or by using the localize method of the desired locale:

<?phpuseICanBoogie\CLDR\LocalizedDateTime;
/* @var $repository \ICanBoogie\CLDR\Repository */$ldt = newLocalizedDateTime(new \DateTime('2013-11-04 20:21:22 UTC'), $repository->locales['fr']);
# or$ldt = $repository->locales['fr']->localize(new \DateTime('2013-11-04 20:21:22 UTC'));
echo$ldt->as_full; // lundi 4 novembre 2013 à 20:21:22 UTC# orecho$ldt->format_as_full(); // lundi 4 novembre 2013 à 20:21:22 UTCecho$ldt->as_long; // 4 novembre 2013 à 20:21:22 UTCecho$ldt->as_medium; // 4 nov. 2013 20:21:22echo$ldt->as_short; // 04/11/2013 20:21

Number formatting

NumberFormatter can be used to format numbers.

<?phpuseICanBoogie\CLDR\NumberFormatter;
$formatter = newNumberFormatter;
$formatter(4123.37, "#,#00.#0");
// 4,123.37$formatter(.3789, "#0.#0 %");
// 37.89 %

Note: You can also obtain a number formatter, or format a number from the repository.

<?php/* @var $repository \ICanBoogie\CLDR\Repository */$number_formatter = $repository->number_formatter;
echo$repository->format_number(4123.37, "#,#00.#0"); // 4,123.37

Localized number formatting

A localized number formatter can be obtained with the localize() method (if the instance was created with a repository), or the localize() method of the desired locale. By default, the list is formatted with the standard type, but you can also provide your own pattern.

<?phpuseICanBoogie\CLDR\NumberFormatter;
useICanBoogie\CLDR\LocalizedNumberFormatter;
/* @var $repository \ICanBoogie\CLDR\Repository */$formatter = newNumberFormatter($repository);
$localized_formatter = $repository->locales['fr']->localize($formatter);
# or$localized_formatter = newLocalizedNumberFormatter($formatter, $repository->locales['fr']);
$localized_formatter(123456.78);
// 123 456,78$repository->locales['en']->localize($formatter)->format(123456.78);
// 123,456.78

Note: You can also obtain a localized number formatter, or format a number from a locale.

<?php/* @var $repository \ICanBoogie\CLDR\Repository */$localized_number_formatter = $repository->locales['fr']->number_formatter;
echo$repository->locales['fr']->format_number(123456.78);

List formatting

ListFormatter can be used to format variable-length lists of things such as "Monday, Tuesday, Friday, and Saturday".

<?phpnamespaceICanBoogie\CLDR;
$list_patterns = Locale\ListPattern::from([
'start' => "{0}, {1}",
'middle' => "{0}, {1}",
'end' => "{0}, and {1}",
'2' => "{0} and {1}"
]);
$formatter = newListFormatter;
$formatter([ "Monday" ], $list_patterns);
// Monday$formatter([ "Monday", "Tuesday" ], $list_patterns);
// Monday and Tuesday$formatter([ "Monday", "Tuesday", "Friday" ], $list_patterns);
// Monday, Tuesday, and Friday$formatter([ "Monday", "Tuesday", "Friday", "Saturday" ], $list_patterns);
// Monday, Tuesday, Friday, and Saturday

Note: You can also obtain a list formatter, or format a list from the repository.

<?phpnamespaceICanBoogie\CLDR;
/* @var $repository Repository */$list_patterns = Locale\ListPattern::from([
'2' => "{0} and {1}",
'start' => "{0}, {1}",
'middle' => "{0}, {1}",
'end' => "{0}, and {1}",
]);
$list_formatter = $repository->list_formatter;
echo$repository->format_list([ "Monday", "Tuesday", "Friday" ], $list_patterns);

Localized list formatting

A localized list formatter can be obtained with the localize() method (if the instance was created with a repository), or the localize() method of the desired locale. By default, the list is formatted with the "standard" type, but more types are available, and you can also provide your own list patterns.

<?phpnamespaceICanBoogie\CLDR;
/* @var $repository \ICanBoogie\CLDR\Repository */$formatter = newListFormatter($repository);
$localized_formatter = $repository->locales['fr']->localize($formatter);
# or$localized_formatter = newLocalizedListFormatter($formatter, $repository->locales['fr']);
$localized_formatter([ "lundi", "mardi", "vendredi", "samedi" ]);
# or$localized_formatter([ "lundi", "mardi", "vendredi", "samedi" ], 'standard');
# or$localized_formatter([ "lundi", "mardi", "vendredi", "samedi" ], LocalizedListFormatter::TYPE_STANDARD);
// lundi, mardi, vendredi et samedi

Note: You can also obtain a localized list formatter, or format a list from a locale.

<?phpnamespaceICanBoogie\CLDR;
/* @var $repository Repository */$localized_list_formatter = $repository->locales['fr']->list_formatter;
echo$repository->locales['fr']->format_list([ "Monday", "Tuesday", "Friday" ]);

Units

Quantities of units such as years, months, days, hours, minutes and seconds can be formatted— for example, in English, "1 day" or "3 days". It's easy to make use of this functionality via a locale's units:

<?php/* @var $repository \ICanBoogie\CLDR\Repository */$units = $repository->locales['en']->units;
echo$units->duration_hour->name; // hoursecho$units->duration_hour->short_name; // hecho$units->duration_hour(1); // 1 hourecho$units->duration_hour(23); // 23 hoursecho$units->duration_hour(23)->as_short; // 23 hrecho$units->duration_hour(23)->as_narrow; // 23h

Many units are available.

Per unit

Combination of units, such as miles per hour or liters per second, can be created. Some units already have 'precomputed' forms, such as kilometer_per_hour; where such units exist, they should be used in preference.

<?php/* @var $repository \ICanBoogie\CLDR\Repository */$units = $repository->locales['en']->units;
echo$units->volume_liter(12.345)->per($units->duration_hour); // 12.345 liters per hourecho$units->volume_liter(12.345)->per($units->duration_hour)->as_short; // 12.345 Lphecho$units->volume_liter(12.345)->per($units->duration_hour)->as_narrow; // 12.345l/h

Units in composed sequence

Units may be used in composed sequences, such as 5° 30m for 5 degrees 30 minutes, or 3 ft, 2 in. For that purpose, the appropriate width can be used to compose the units in a sequence.

<?php/* @var $repository \ICanBoogie\CLDR\Repository */$units = $repository->locales['en']->units;
$units->sequence
->angle_degree(5)
->duration_minute(30)
->as_narrow;
// 5° 30m$units->sequence
->length_foot(3)
->length_inch(2)
->as_short;
// 3 ft, 2 in$units = $repository->locales['fr']->units;
$units->sequence
->duration_hour(12)
->duration_minute(34)
->duration_second(45)
->as_long;
// 12 heures, 34 minutes et 56 secondes$units->sequence
->duration_hour(12)
->duration_minute(34)
->duration_second(45)
->as_short;
// 12 h, 34 min et 56 s$units->sequence
->duration_hour(12)
->duration_minute(34)
->duration_second(45)
->as_narrow;
// 12h 34m 56s

Plurals

Languages have different pluralization rules for numbers that represent zero, one, tow, few, many or other. ICanBoogie's CLDR makes it easy to find the plural rules for any numeric value:

<?php/* @var $repository \ICanBoogie\CLDR\Repository */$repository->plurals->rules_for('fr'); // [ 'one', 'other' ]$repository->plurals->rules_for('ar'); // [ 'zero', 'one', 'two', 'few', 'many', 'other' ]$repository->plurals->rule_for(1.5, 'fr'); // one$repository->plurals->rule_for(2, 'fr'); // other$repository->plurals->rule_for(2, 'ar'); // two

Territories

The information about a territory is represented by a Territory instance, which aggregates information that is actually scattered across the CLDR.

<?php/* @var $repository \ICanBoogie\CLDR\Repository */$territory = $repository->territories['FR'];
echo$territory; // FRecho$territory->currency; // EURecho$territory->currency_at('1977-06-06'); // FRFecho$territory->currency_at('now'); // EURecho$territory->language; // frecho$territory->population; // 66259000echo$territory->name_as('fr-FR'); // Franceecho$territory->name_as('it'); // Franciaecho$territory->name_as('ja'); // フランスecho$territory->name_as_fr_FR; // Franceecho$territory->name_as_it; // Franciaecho$territory->name_as_ja; // フランスecho$repository->territories['FR']->first_day; // monecho$repository->territories['EG']->first_day; // satecho$repository->territories['BS']->first_day; // sunecho$repository->territories['AE']->weekend_start; // friecho$repository->territories['AE']->weekend_end; // sat

Localized territories

A localized territory can be obtained with the localize() method, or the localize() method of the desired locale.

<?php/* @var $repository \ICanBoogie\CLDR\Repository */$territory = $repository->territories['FR'];
$localized_territory = $territory->localize('fr');
# or$localized_territory = $repository->locales['fr']->localize($territory);
echo$territory->localize('fr')->name; // Franceecho$territory->localize('it')->name; // Franciaecho$territory->localize('ja')->name; // フランス

Currencies

Currencies are represented by instances of Currency. You can create the instance yourself or get one through the currency collection.

<?phpuseICanBoogie\CLDR\Currency;
/* @var $repository \ICanBoogie\CLDR\Repository */$euro = newCurrency($repository, 'EUR');
# or$euro = $repository->currencies['EUR'];

Localized currencies

A localized currency can be obtained with the localize() method, or the localize() method of the desired locale, it is often used to format a currency using the convention of a locale.

<?phpuseICanBoogie\CLDR\Currency;
/* @var $repository \ICanBoogie\CLDR\Repository */$currency = newCurrency($repository, 'EUR');
$localized_currency = $currency->localize('fr');
# or$localized_currency = $repository->locales['fr']->localize($currency);
echo$localized_currency->name; // euroecho$localized_currency->name(1); // euroecho$localized_currency->name(10); // eurosecho$localized_currency->format(12345.67); // 12 345,67 €
