php如何获取给定语言环境的当前十进制/千位分隔符

I've set the locale using the setlocale() function to let's say "en_US".

now I'm trying to format the currency without a thousand separator like this:

$currency = number_format($value, 2, '.', '');

that works, but sometimes I have other currencies and I want the number_format to use the correct decimal separator according to the use locale.

Is there a way to get the current decimal separator somehow, based on the locale that has been set?

localeconv() should do it. From the manual:

Returns an associative array containing localized numeric and monetary formatting information.

Here is a list of language strings recognized by setlocale() on Windows.

Sean Bright is right, use localeconv() function. Are you sure that you set a correct locale for your OS, because Unix-based OS use "en_US.UTF-8" like notation, while Windows use "en-US".

It is not the best, but it works:

$locale_info = localeconv();
echo 'decimal_point=', $locale_info['decimal_point'], '<br/>/n';

localeconv() returns an associative array with other fields besides the decimal point character.
