php - 如何在 PHP 中以印度编号格式显示货币？

Question

我有一个关于格式化卢比货币(印度卢比 - INR)的问题。

例如，这里的数字表示为:

1
10
100
1,000
10,000
1,00,000
10,00,000
1,00,00,000
10,00,00,000

请参阅 Indian Numbering System

我必须使用 PHP。

我看到了这个问题 Displaying Currency in Indian Numbering Format .但是我的问题无法为 PHP 获取它。

如何使用money_format()印度货币格式？

Answer 1

您有很多选择，但是money_format可以为您解决问题。

例子:

$amount = '100000';
setlocale(LC_MONETARY, 'en_IN');
$amount = money_format('%!i', $amount);
echo $amount;

输出:

1,00,000.00

注意:

The function money_format() is only defined if the system has strfmon capabilities. For example, Windows does not, so money_format() is undefined in Windows.

纯 PHP 实现 - 适用于任何系统:

$amount = '10000034000';
$amount = moneyFormatIndia( $amount );
echo $amount;

function moneyFormatIndia($num) {
    $explrestunits = "" ;
    if(strlen($num)>3) {
        $lastthree = substr($num, strlen($num)-3, strlen($num));
        $restunits = substr($num, 0, strlen($num)-3); // extracts the last three digits
        $restunits = (strlen($restunits)%2 == 1)?"0".$restunits:$restunits; // explodes the remaining digits in 2's formats, adds a zero in the beginning to maintain the 2's grouping.
        $expunit = str_split($restunits, 2);
        for($i=0; $i<sizeof($expunit); $i++) {
            // creates each of the 2's group and adds a comma to the end
            if($i==0) {
                $explrestunits .= (int)$expunit[$i].","; // if is first value , convert into integer
            } else {
                $explrestunits .= $expunit[$i].",";
            }
        }
        $thecash = $explrestunits.$lastthree;
    } else {
        $thecash = $num;
    }
    return $thecash; // writes the final format where $currency is the currency symbol.
}
