有没有一种简单的方法将数字转换为PHP中的单词？
在PHP中，是否有一种简单的方法将数字转换为单词？ 比如27日到27日 。
我发现了一些（2007/2008）源代码在线，因为它是版权，但我可以自由使用和修改，但我想，所以我把它放在这里，并在CC-Wiki下重新授权：

我find了两个链接。 首先是一个免费的PHP类，你可以使用， 第二个是一个示例函数，你可以看看和复制或使用自己写。
有没有我知道的内置方式，但如果你看看我的这个问题的示例代码（在C＃中）应该很容易让你工作。 基本上它只是一个解开variables和添加$前缀在适当的问题，它应该工作。
我重写了上面的代码，以适应标准的美国文字编号格式。
function singledigit($number){ switch($number){ case 0:$word = "zero";break; case 1:$word = "one";break; case 2:$word = "two";break; case 3:$word = "three";break; case 4:$word = "four";break; case 5:$word = "five";break; case 6:$word = "six";break; case 7:$word = "seven";break; case 8:$word = "eight";break; case 9:$word = "nine";break; } return $word; } function doubledigitnumber($number){ if($number == 0){ $word = ""; } else{ $word = "-".singledigit($number); } return $word; } function doubledigit($number){ switch($number[0]){ case 0:$word = doubledigitnumber($number[1]);break; case 1: switch($number[1]){ case 0:$word = "ten";break; case 1:$word = "eleven";break; case 2:$word = "twelve";break; case 3:$word = "thirteen";break; case 4:$word = "fourteen";break; case 5:$word = "fifteen";break; case 6:$word = "sixteen";break; case 7:$word = "seventeen";break; case 8:$word = "eighteen";break; case 9:$word = "ninteen";break; }break; case 2:$word = "twenty".doubledigitnumber($number[1]);break; case 3:$word = "thirty".doubledigitnumber($number[1]);break; case 4:$word = "forty".doubledigitnumber($number[1]);break; case 5:$word = "fifty".doubledigitnumber($number[1]);break; case 6:$word = "sixty".doubledigitnumber($number[1]);break; case 7:$word = "seventy".doubledigitnumber($number[1]);break; case 8:$word = "eighty".doubledigitnumber($number[1]);break; case 9:$word = "ninety".doubledigitnumber($number[1]);break; } return $word; } function unitdigit($numberlen,$number){ switch($numberlen){ case 3:case 6:case 9:case 12:$word = "hundred";break; case 4:case 5:$word = "thousand";break; case 7:case 8:$word = "million";break; case 10:case 11:$word = "billion";break; } return $word; } function numberToWord($number){ $numberlength = strlen($number); if ($numberlength == 1) { return singledigit($number); }elseif ($numberlength == 2) { return doubledigit($number); } else { $word = ""; $wordin = ""; switch ($numberlength ) { case 5:case 8: case 11: if($number[0] >0){ $unitdigit = unitdigit($numberlength,$number[0]); $word = doubledigit($number[0].$number[1]) ." ".$unitdigit." "; return $word." ".numberToWord(substr($number,2)); } else{ return $word."

".numberToWord(substr($number,1)); } } }
我需要一个解决scheme，把'和'放入返回的string中，并将其格式化为一个句子 – 通常就像人类会说的那样。 所以我稍微调整了一个不同的解决scheme – 张贴我认为这可能是有用的人。
4,835,301 returns "Four million eight hundred and thirty five thousand three hundred and one."

这是我今晚写的一个小class。 注意事项：
- 只有英文。
- 只处理美国/法国数十亿的定义等
-
longform方法不处理小数。 它只是抹去它们。 随意修改这个，如果你愿意，添加这个function。 -
numberformat方法确实会做小数点，但不做任何舍入。 我不得不创build一个新的数字numberformat函数，因为PHP的整数大小固有的限制。 我翻译的数字非常大，当我用number_format()检查我的翻译时，花了30分钟才发现我的翻译没有错，number_format是。 - 这不是关于类的警告，而是关于PHP。 PHP的32位版本不会处理大于
2,147,483,647（20亿和更改）的整数。 64位版本将处理起来像9 quintillion什么的。 但是在这里不重要，只要你把数字作为一个string到longform方法中即可。 我从webform的ajax做了一个306位的数字，只要我把它作为''+number传递给服务器即可。
所以，这个类将把数字翻译成999 Centillion, 999 etc. （例如，一个9个字符长度为306个字符的string）。 任何比这更大的数字，函数只是返回一个愚蠢的消息。
用法：
$number = '999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999'; reallyBig::longform($number);
可选的第二个布尔参数默认为true，这样可以在正确的位置添加逗号，以使数字更具可读性。
顺便说一下，如果您希望将其设置为负数，则可以在前面放置一个字符，但input的string中包含的任何其他字符将被删除。 例如：
reallyBig::longform('-C55LL-M5-4-a-9u7-71m3-M8'); 将输出： negative five billion, five hundred fifty-four million, nine hundred seventy-seven thousand, one hundred thirty-eight
numberformat方法不是其他任何方法所必需的。 如果你想检查一个非常长的翻译的数字，那就在那里。 由于所有这些函数都以string的forms处理数字，所以它们不会遇到PHP的限制。
我停在999厘米的唯一原因是因为centillion是网站上我看到的最后一个数字，当我不记得十亿分之后发生了什么。

使用PHP函数将数字转换为单词的非常简单的方法。
我已经使用recursion函数生成了这个。
