Convert Number to Words in Indian currency format with paise value

I was faced with a requirement to convert number to words/string in Indian naming system with lakhs and crores. I had to generate the amount in words for printing it out on a bill. The total amount, provided to the customer, needed to be converted to string. For example, if 1345673 was to be converted to Thirteen lakh Forty Five Thousand Six Hundred and Seventy Three, these functions will have to be followed.

function getIndianCurrency($number)
{
    $decimal = round($number - ($no = floor($number)), 2) * 100;
    $hundred = null;
    $digits_length = strlen($no);
    $i = 0;
    $str = array();
    $words = array(0 => '', 1 => 'one', 2 => 'two',
        3 => 'three', 4 => 'four', 5 => 'five', 6 => 'six',
        7 => 'seven', 8 => 'eight', 9 => 'nine',
        10 => 'ten', 11 => 'eleven', 12 => 'twelve',
        13 => 'thirteen', 14 => 'fourteen', 15 => 'fifteen',
        16 => 'sixteen', 17 => 'seventeen', 18 => 'eighteen',
        19 => 'nineteen', 20 => 'twenty', 30 => 'thirty',
        40 => 'forty', 50 => 'fifty', 60 => 'sixty',
        70 => 'seventy', 80 => 'eighty', 90 => 'ninety');
    $digits = array('', 'hundred','thousand','lakh', 'crore');
    while( $i < $digits_length ) {
        $divider = ($i == 2) ? 10 : 100;
        $number = floor($no % $divider);
        $no = floor($no / $divider);
        $i += $divider == 10 ? 1 : 2;
        if ($number) {
            $plural = (($counter = count($str)) && $number > 9) ? 's' : null;
            $hundred = ($counter == 1 && $str[0]) ? ' and ' : null;
            $str [] = ($number < 21) ? $words[$number].' '. $digits[$counter]. $plural.' '.$hundred:$words[floor($number / 10) * 10].' '.$words[$number % 10]. ' '.$digits[$counter].$plural.' '.$hundred;
        } else $str[] = null;
    }
    $Rupees = implode('', array_reverse($str));
    $paise = ($decimal) ? "." . ($words[$decimal / 10] . " " . $words[$decimal % 10]) . ' Paise' : '';
    return ($Rupees ? $Rupees . 'Rupees ' : '') . $paise;
}

echo getIndianCurrency(79855995.19);

output seven crore ninety eight lakhs fifty five thousands nine hundred and ninety five Rupees .one nine Paise
