Example #1 numfmt_set_text_attribute() example
<?php
$fmt = numfmt_create ( 'de_DE' , NumberFormatter :: DECIMAL );
echo "Prefix: " . numfmt_get_text_attribute ( $fmt , NumberFormatter :: NEGATIVE_PREFIX ). "\n" ;
echo numfmt_format ( $fmt , - 1234567.891234567890000 ). "\n" ;
numfmt_set_text_attribute ( $fmt , NumberFormatter :: NEGATIVE_PREFIX , "MINUS" );
echo "Prefix: " . numfmt_get_text_attribute ( $fmt , NumberFormatter :: NEGATIVE_PREFIX ). "\n" ;
echo numfmt_format ( $fmt , - 1234567.891234567890000 ). "\n" ;
?>
Example #2 OO example
<?php
$fmt = new NumberFormatter ( 'de_DE' , NumberFormatter :: DECIMAL );
echo "Prefix: " . $fmt -> getTextAttribute ( NumberFormatter :: NEGATIVE_PREFIX ). "\n" ;
echo $fmt -> format (- 1234567.891234567890000 ). "\n" ;
$fmt -> setTextAttribute ( NumberFormatter :: NEGATIVE_PREFIX , "MINUS" );
echo "Prefix: " . $fmt -> getTextAttribute ( NumberFormatter :: NEGATIVE_PREFIX ). "\n" ;
echo $fmt -> format (- 1234567.891234567890000 ). "\n" ;
?>
以上例程会输出:
Prefix: - -1.234.567,891 Prefix: MINUS MINUS1.234.567,891
