How to display Currency in Indian Numbering Format in PHP?

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.}

$num = 1234567890.123;$num = preg_replace("/(\d+?)(?=(\d\d)+(\d)(?!\d))(\.\d+)?/i", "$1,", $num);echo $num;// Input : 1234567890.123// Output : 1,23,45,67,890.123// Input : -1234567890.123// Output : -1,23,45,67,890.123

echo 'Rs. '.IND_money_format(1234567890);function IND_money_format($money){    $len = strlen($money);    $m = '';    $money = strrev($money);    for($i=0;$i<$len;$i++){        if(( $i==3 || ($i>3 && ($i-1)%2==0) )&& $i!=$len){            $m .=',';        }        $m .=$money[$i];    }    return strrev($m);}

NOTE:: it is not tested on float values and it suitable for only Integer
