// three hundred and thirteen rupees and seventy-six paise
echo getIndianCurrency(313.76);

function getIndianCurrency(float $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 = '';

    if ($decimal) {
        $paise = 'and ';
        $decimal_length = strlen($decimal);

        if ($decimal_length == 2) {
            if ($decimal >= 20) {
                $dc = $decimal % 10;
                $td = $decimal - $dc;
                $ps = ($dc == 0) ? '' : '-' . $words[$dc];

                $paise .= $words[$td] . $ps;
            } else {
                $paise .= $words[$decimal];
            }
        } else {
            $paise .= $words[$decimal % 10];
        }

        $paise .= ' paise';
    }

    return ($rupees ? $rupees . 'rupees ' : '') . $paise ;
}

Uses:

echo getIndianCurrency(313.76);

Output:

three hundred and thirteen rupees and seventy-six paise
