NumberFormatter::create -- numfmt_create -- NumberFormatter::__construct — Create a number formatter
Object oriented style (method)
Procedural style
Object oriented style (constructor):
Creates a number formatter.
Locale in which the number would be formatted (locale name, e.g. en_CA).
Style of the formatting, one of the format style constants. If NumberFormatter::PATTERN_DECIMAL or NumberFormatter::PATTERN_RULEBASED is 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 string in case chosen style requires pattern.
Returns NumberFormatter object or FALSE on error.
Beispiel #1 numfmt_create() example
<?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";
?>
Beispiel #2 NumberFormatter::create() example
<?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";
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
1.234.567,891 millicentoquarantadue
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.
