<?php
$fmt = numfmt_create( 'de_DE', NumberFormatter::DECIMAL );
$num = "1.234.567,891";
echo numfmt_parse($fmt, $num)."\n";
echo numfmt_parse($fmt, $num, NumberFormatter::TYPE_INT32)."\n";
?>
示例 #2 OO example
<?php
$fmt = new NumberFormatter( 'de_DE', NumberFormatter::DECIMAL );
$num = "1.234.567,891";
echo $fmt->parse($num)."\n";
echo $fmt->parse($num, NumberFormatter::TYPE_INT32)."\n";
?>
以上例程会输出：
