如何使用 PHP 将十进制数转换为单词（货币格式）？

我这里只需要一点帮助。因为我正在创建一个代码，用于将小数转换为单词中的货币格式。例如如果

我有这个号码

'2143.45'

输出应该是

“两千一百四十三又四十五美分”

我找到了这样的代码，但我不知道如何包含美分。

<?php

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

    $output = "";

    if ($integer{0} == "-")
    {
        $output = "negative ";
        $integer    = ltrim($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); $z++)
        {
            if ($groups2[$z] != "")

 $num = 500254.89;
 $test = convertNumber($num);

 echo $test;

?>

有一个梨库可以做到这一点。

EDIT

或者您可以在代码末尾执行此操作

echo $test . ' cents';
