Answer 1

You can't just simply do it like that, you need to convert them to normal digits first:

class Converter 
{
    public static $bn = ["১", "২", "৩", "৪", "৫", "৬", "৭", "৮", "৯", "০"];
    public static $en = ["1", "2", "3", "4", "5", "6", "7", "8", "9", "0"];

    public static function bn2en($number)
    {
        return str_replace(self::$bn, self::$en, $number);
    }

    public static function en2bn($number)
    {
        return str_replace(self::$en, self::$bn, $number);
    }
}

$a = '১২'; //(12)
$b = '৫'; //(5)

$c = Converter::bn2en($a) + Converter::bn2en($b); // $c = 17
echo Converter::en2bn($c); // ১৭

Answer 2

another approach by using intl extension :

// create a format from ba local
// you can get all available locales by : print_r(IntlCalendar::getAvailableLocales());
$format = numfmt_create('ba', NumberFormatter::DECIMAL);

$a = numfmt_parse($format, '১২');
$b = numfmt_parse($format, '৫');
echo $c = $a + $b;

Output : 17
