將錢轉換爲PHP中的文本

這是您的開始。這是我後來寫的一個遞歸函數（解決Project Euler problem 17的一部分），它將數字轉換爲字母......它可以處理一些相當大的數字;）

所有你需要做的就是添加美元和美分以及根據需要修改。所以基本上你必須爲美元數量調用一次函數，爲美分數量調用一次。我不認爲這有一個原生的PHP功能。你必須使用一個庫（比如梨）功能。

（你可以看到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.

不，我相信你需要自己寫一個。實現起來相當簡單，但有一些角落案例需要處理。
