因为显然“不”不是这个问题的正确答案。
»摘要
PEAR Numbers_Words 包提供拼写方法 用数字表示。
答案 1 :(得分：3)
这是一个开始。这是我后来写的一个递归函数（解决Project Euler problem 17的一部分）将数字转换为字母......它可以处理一些非常大的数字;）
您需要做的就是添加美元和美分组件并根据需要进行修改。所以基本上你必须为美元金额调用一次函数，对美分组件调用一次。我不认为这有一个原生的PHP功能。您必须使用库（如Pear）函数。
（您可以看到the function in action)：
<?php
function translateToWords($number)
{
/*****
* A recursive function to turn digits into words
* Numbers must be integers from -999,999,999,999 to 999,999,999,999 inclussive.

答案 2 :(得分：1)
不，我相信你需要自己写一个。它实现起来非常简单，但是你需要处理一些极端情况。
答案 3 :(得分：0)
不，PHP中没有这样的功能。最简单的方法是下载一些代码from the internet。
