php - 如何在 PHP 中总结两个 Bangla (UTF-8) 数字？

Question

我需要对两个 utf-8 孟加拉数字求和。这是代码:

<?php 
$a = ১২; //(12)
$b = ৫; //(5)
echo $c = $a + $b; //OUTPUR 17
?>

我需要 outpur 但现在它显示 0 那么我该怎么做呢？提前感谢所有

你不能就这么简单，你需要先把它们转换成普通数字:

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
