如果我使用此代码并调用该函数：

echo convertNumber(72253.80)." ONLY";

它返回seventy-two thousand, two hundred and fifty-three CENTS eight ONLY，但我需要它返回八十而不是八。

同样适用于：

echo convertNumber(72253.25)." ONLY";

返回seventy-two thousand, two hundred and fifty-three CENTS two five ONLY，但我需要它返回二十五而不是二五。

您为小数位调用了错误的函数，本节在这里：

if($dec > 0)
{ 
   $output .= " CENTS";
   for($i = 0; $i < strlen($dec); $i++) $output .= " ".convertDigit($dec{$i});
}

需要是：

if($dec > 0)
{
   $output .= " CENTS";
   $output .= " ".convertTwoDigit($dec{0},$dec{1});
}
