How to display Currency in Indian Numbering Format in PHP

Question

I have a question about formatting the Rupee currency (Indian Rupee - INR).

For example, numbers here are represented as:

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


        

Answer 1

You have so many options but money_format can do the trick for you.

Example:

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

Output:

1,00,000.00

Note:

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.

Pure PHP Implementation - Works on any system:

$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.
}

Answer 2

When money_format is not available :

function format($amount): string
{
    list ($number, $decimal) = explode('.', sprintf('%.2f', floatval($amount)));

    $sign = $number < 0 ? '-' : '';

    $number = abs($number);

    for ($i = 3; $i < strlen($number); $i += 3)
    {
        $number = substr_replace($number, ',', -$i, 0);
    }

    return $sign . $number . '.' . $decimal;

}

Answer 3

I have used different format parameters to money_format() for my output.

setlocale(LC_MONETARY, 'en_IN');
if (ctype_digit($amount) ) {
     // is whole number
     // if not required any numbers after decimal use this format 
     $amount = money_format('%!.0n', $amount);
}
else {
     // is not whole number
     $amount = money_format('%!i', $amount);
}
//$amount=10043445.7887 outputs 1,00,43,445.79
//$amount=10043445 outputs 1,00,43,445

Answer 4

Simply use below function to format in INR.

function amount_inr_format($amount) {
    $fmt = new \NumberFormatter($locale = 'en_IN', NumberFormatter::DECIMAL);
    return $fmt->format($amount);
}

Answer 5

This for both integer and float values

    function indian_money_format($number)
    {

        if(strstr($number,"-"))
        {
            $number = str_replace("-","",$number);
            $negative = "-";
        }

        $split_number = @explode(".",$number);

        $rupee = $split_number[0];
        $paise = @$split_number[1];

        if(@strlen($rupee)>3)
        {
            $hundreds = substr($rupee,strlen($rupee)-3);
            $thousands_in_reverse = strrev(substr($rupee,0,strlen($rupee)-3));
            $thousands = '';
            for($i=0; $i<(strlen($thousands_in_reverse)); $i=$i+2)
            {
                $thousands .= $thousands_in_reverse[$i].$thousands_in_reverse[$i+1].",";
            }
            $thousands = strrev(trim($thousands,","));
            $formatted_rupee = $thousands.",".$hundreds;

        }
        else
        {
            $formatted_rupee = $rupee;
        }

        if((int)$paise>0)
        {
            $formatted_paise = ".".substr($paise,0,2);
        }else{
            $formatted_paise = '.00';
        }

        return $negative.$formatted_rupee.$formatted_paise;

    }

Answer 6

It's my very own function to do the task

function bd_money($num) {
    $pre = NULL; $sep = array(); $app = '00';
    $s=substr($num,0,1);
    if ($s=='-') {$pre= '-';$num = substr($num,1);}
    $num=explode('.',$num);
    if (count($num)>1) $app=$num[1];
    if (strlen($num[0])<4) return $pre . $num[0] . '.' . $app;
    $th=substr($num[0],-3);
    $hu=substr($num[0],0,-3);
    while(strlen($hu)>0){$sep[]=substr($hu,-2); $hu=substr($hu,0,-2);}
    return $pre.implode(',',array_reverse($sep)).','.$th.'.'.$app;
}

It took 0.0110 Seconds per THOUSAND query while number_format took 0.001 only. Always try to use PHP native functions only when performance is target issue.
