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

Use this function:

function addCommaToRs($amt, &$ret, $dec='', $sign=''){
    if(preg_match("/-/",$amt)){
        $amts=explode('-',$amt);
        $amt=$amts['1'];
        static $sign='-';
    } 
    if(preg_match("/\./",$amt)){
        $amts=explode('.',$amt);
        $amt=$amts['0'];
        $l=strlen($amt);
        static $dec;
        $dec=$amts['1'];
    } else {
        $l=strlen($amt);
    }
    if($l>3){
        if($l%2==0){
            $ret.= substr($amt,0,1);
            $ret.= ",";
            addCommaToRs(substr($amt,1,$l),$ret,$dec);
        } else{
            $ret.=substr($amt,0,2);
            $ret.= ",";     
            addCommaToRs(substr($amt,2,$l),$ret,$dec);
        }
    } else {
        $ret.= $amt;
        if($dec) $ret.=".".$dec;
    }
    return $sign.$ret; 
}

Call it like this:

$amt = '';
echo addCommaToRs(123456789.123,&$amt,0);

This will return 12,34,567.123.
