NumberFormatter::create -- numfmt_create -- NumberFormatter::__constructСоздаёт средство форматирования чисел

Описание

Объектно-ориентированный стиль (метод)

public static NumberFormatter::create(string $locale, int $style, ?string $pattern = null): ?NumberFormatter

Процедурный стиль

numfmt_create(string $locale, int $style, ?string $pattern = null): ?NumberFormatter

Объектно-ориентированный стиль (конструктор):

public NumberFormatter::__construct(string $locale, int $style, ?string $pattern = null)

Создаёт средство форматирования чисел.

Список параметров

locale

Локаль, в которой будет отформатировано число (название локали, например en_CA).

style

Стиль форматирования, одна из констант стиля форматирования. Если передана NumberFormatter::PATTERN_DECIMAL или NumberFormatter::PATTERN_RULEBASED, то формат числа открывается с использованием данного шаблона, который должен соответствовать синтаксису, описанному в » документации ICU DecimalFormat или » документации ICU RuleBasedNumberFormat, соответственно.

pattern

Строка шаблона, если для выбранного стиля требуется шаблон.

Возвращаемые значения

Возвращает объект NumberFormatter или null в случае возникновения ошибки.

Список изменений

Версия Описание
8.0.0 pattern теперь допускает значение null.

Примеры

Пример #1 Пример использования numfmt_create()

<?php
$fmt
= numfmt_create( 'de_DE', NumberFormatter::DECIMAL );
echo
numfmt_format($fmt, 1234567.891234567890000)."\n";
$fmt = numfmt_create( 'it', NumberFormatter::SPELLOUT );
echo
numfmt_format($fmt, 1142)."\n";
?>

Пример #2 Пример использования NumberFormatter::create()

<?php
$fmt
= new NumberFormatter( 'de_DE', NumberFormatter::DECIMAL );
echo
$fmt->format(1234567.891234567890000)."\n";
$fmt = new NumberFormatter( 'it', NumberFormatter::SPELLOUT );
echo
$fmt->format(1142)."\n";
?>

When formatting durations using the NumberFormatter::DURATION type, you may also need to use NumberFormatter::setTextAttribute to get the desired output.

<?php

$fmt
= new NumberFormatter('en', NumberFormatter::DURATION);
// Outputs: string(7) "3:25:45"
var_dump($fmt->format(12345));

// "%in-numerals" is the default ruleset, so this results in the same as above.
$fmt->setTextAttribute(NumberFormatter::DEFAULT_RULESET, "%in-numerals");
// Outputs: string(7) "3:25:45"
var_dump($fmt->format(12345));

$fmt->setTextAttribute(NumberFormatter::DEFAULT_RULESET, "%with-words");
// Outputs: string(31) "3 hours, 25 minutes, 45 seconds"
var_dump($fmt->format(12345));

$fmt2 = new NumberFormatter('fr', NumberFormatter::DURATION);
// Outputs: string(7) "12 345"
// See notes below.
var_dump($fmt2->format(12345));

?>

This is a little counter-intuitive because there is not much doc available about the DURATION type.

Also, as far as I can tell, only the English (en) locale has support for the "%in-numerals" & "%with-words" rulesets. Other locales seem to simply format the input as if the DECIMAL type had been used (at least using "fr" or "de" as the target locale).

One way to provide that feature across different locales is to extract the ruleset implicitely used by NumberFormatter::DURATION and adapt it for the locales you're targetting. Use NumberFormatter::getPattern to extract the ruleset.

Although there are ORDINAL and SPELLOUT formatters, it's not possible to join these together to turn "2" into "second". You'll either get "2nd", or "two", or something unexpected if you try to use bitwise operators.

It should be noted that the locale string passed into NumberFormatter's constructor doesn't play with UCA keywords quite as readily as, say, the Collator and IntlDateFormatter classes' constructors.

According to the Unicode spec (http://www.unicode.org/reports/tr35), I should be able to specify a locale of "ja_JP@numbers=jpanfin" which, for spellout mode, should give me Japanese financial (ie. anti-forgery) numerals. When passed into NumberFormatter's constructor, "ja_JP@numbers=jpanfin" doesn't work.

However, when I look at a dump of NumberFormatter::getPattern() for the ja_JP locale, I see that the financial numerals *are* in there (as %financial). Here's how we wrangle them out of the NumberFormatter:

<?php
$number
= 1234567890;

$formatter = new NumberFormatter('ja_JP', NumberFormatter::SPELLOUT);

$formatter->setTextAttribute(NumberFormatter::DEFAULT_RULESET, "%financial");

echo
$formatter->format($number);
//above gives [拾弐億参千四百伍拾六萬七千八百九拾] (as opposed to [十二億三千四百五十六万七千八百九十]) - bingo!
