Список параметров
-
locale -
Locale in which the number would be formatted (locale name, e.g. en_CA).
-
style -
Style of the formatting, one of the format style constants. If
NumberFormatter::PATTERN_DECIMALorNumberFormatter::PATTERN_RULEBASEDis passed then the number format is opened using the given pattern, which must conform to the syntax described in » ICU DecimalFormat documentation or » ICU RuleBasedNumberFormat documentation, respectively. -
pattern -
Pattern string if the chosen style requires a pattern.
Возвращаемые значения
Returns NumberFormatter object or FALSE on error.

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.
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!
?>
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.
