Example #1 numfmt_get_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
