Example #1 numfmt_parse() example
<?php$fmt = numfmt_create( 'de_DE', NumberFormatter::DECIMAL );$num = "1.234.567,891";echo numfmt_parse($fmt, $num)."\n";echo numfmt_parse($fmt, $num, NumberFormatter::TYPE_INT32)."\n";?>
Example #2 OO example
<?php$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";?>
