How to convert decimal number to words (money format) using PHP?

Question

I just need a little help here. Because I am creating a code for converting decimals to Money format in words. For example if

I have this number

'2143.45'

the output should be

'two thousand one hundred forty three and forty-five cents'

I found a code like this but I don't have an idea how to include cents.

<?php

function convertNumber($number)
{
    list($integer, $fraction) = explode(".", (string) $number);

    $output = "";

    if ($integer{0} == "-")
    {

        $integer    = ltrim($integer, "-");
    }
    else if ($integer{0} == "+")
    {
        $output = "positive ";
        $integer    = ltrim($integer, "+");
    }

    if ($integer{0} == "0")
    {
        $output .= "zero";
    }
    else
    {
        $integer = str_pad($integer, 36, "0", STR_PAD_LEFT);
        $group   = rtrim(chunk_split($integer, 3, " "), " ");
        $groups  = explode(" ", $group);

        $groups2 = array();
        foreach ($groups as $g)
        {
            $groups2[] = convertThreeDigit($g{0}, $g{1}, $g{2});

        for ($z = 0; $z < count($groups2); $z++)

I don't know about cents but I have created code for Indian Rupees.

    $decimal_length = strlen($decimal);
    $i = 0;
    $str = array();
    $str2 = array();
    $words = array(0 => '', 1 => 'one', 2 => 'two',
        3 => 'three', 4 => 'four', 5 => 'five', 6 => 'six',

    $Rupees = implode('', array_reverse($str));
    $paise = implode('', array_reverse($str2));
    $paise = ($decimal_part > 0) ? $paise . ' Paise' : '';
    return ($Rupees ? $Rupees . 'Rupees ' : '') . $paise;
}
?>

Output:

two thousand eight hundred and fifty one Rupees five Paise

you can use this by

echo numtowords(156.50);

output is

One Hundred Fifty Six peso/s and Fifty centavo/s only.
