范例
Example #1 numfmt_set_attribute() example
<?php$fmt = numfmt_create( 'de_DE', NumberFormatter::DECIMAL );echo "Digits: ".numfmt_get_attribute($fmt, NumberFormatter::MAX_FRACTION_DIGITS)."\n";echo numfmt_format($fmt, 1234567.891234567890000)."\n";numfmt_set_attribute($fmt, NumberFormatter::MAX_FRACTION_DIGITS, 2);echo "Digits: ".numfmt_get_attribute($fmt, NumberFormatter::MAX_FRACTION_DIGITS)."\n";echo numfmt_format($fmt, 1234567.891234567890000)."\n";?>
Example #2 OO example
<?php$fmt = new NumberFormatter( 'de_DE', NumberFormatter::DECIMAL );echo "Digits: ".$fmt->getAttribute(NumberFormatter::MAX_FRACTION_DIGITS)."\n";echo $fmt->format(1234567.891234567890000)."\n";$fmt->setAttribute(NumberFormatter::MAX_FRACTION_DIGITS, 2);echo "Digits: ".$fmt->getAttribute(NumberFormatter::MAX_FRACTION_DIGITS)."\n";echo $fmt->format(1234567.891234567890000)."\n";?>
以上例程会输出：
Digits: 3 1.234.567,891 Digits: 2 1.234.567,89
