您可以建立一个功能落后读取次数，并写下文字，加入“hundreed”或取决于什么样的功能，目前的数字之前发现“tousend”。 – 2014-09-08 14:29:55

有没有我知道的内置方式，但如果你看看我的示例代码this question（在C＃中），它应该很容易让你工作。基本上它只是解决变量的问题，并在适当的地方添加$前缀，它应该可以工作。

或者，您可以在PHP中使用NumberFormatter类从intl包。这里有一个示例代码来让你开始（对于命令行）：

<?php 
if ($argc < 3) 
    { 
    echo "usage: php {$argv[0]} lang-tag number ...\n"; 
    exit; 
    } 

array_shift($argv); 
$lang_tag = array_shift($argv); 

$nf1 = new NumberFormatter($lang_tag, NumberFormatter::DECIMAL); 
$nf2 = new NumberFormatter($lang_tag, NumberFormatter::SPELLOUT); 

foreach ($argv as $num) 
    { 
    echo $nf1->format($num).' is '.$nf2->format($num)."\n"; 
    }

这里有一个小的类，我写在今晚。注意事项：

只有英文。
只处理美国/法国对数十亿等的定义
longform方法不处理小数。它只是抹去它们。如果您愿意，可以随意修改并添加该功能。
numberformat方法不会做小数点，但不做任何舍入。由于PHP整数大小的固有限制，我不得不创建一个新的numberformat函数。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。
这不是关于该类的警告，而是关于PHP。 32位版本的PHP不会处理大于2,147,483,647（20亿和更改）的整数。 64位版本将处理高达像9 quintillion什么的。但只要您将longform方法的数字以string的形式输入，此处无关紧要。我从网络表格中完成了一个306位数字，超过ajax，只要我将它作为''+number传递给服务器即可。

所以，这个类将把数字翻译到999 Centillion, 999 etc.（例如，一个9个字符长度为306个字符的字符串）。任何比这更大的数字，该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，这增加了逗号作为最好的可以在适当的地方，以使号码更易读。

顺便说一下，如果您希望它为负数，则可以将-放在前面，但输入字符串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

的numberformat方法是没有必要的任何其它方法。如果你想检查一个非常长的翻译数字，那就在那里。由于所有这些函数都以字符串形式处理数字，因此它们不会遇到PHP的限制。

我停在999厘米的唯一原因是因为centillion是我在查看网站时的最后一个数字，当时我不记得十亿分之后发生了什么。

我需要的是把“及”到返回字符串并格式化成一个句子的解决方案 - 通常是作为一个人会说出来。所以我稍微修改了一个不同的解决方案 - 因为我认为这可能对某人有用。

4,835,301 returns "Four million eight hundred and thirty five thousand three hundred and one."

Amount in Words:</b><?=no_to_words($number)?>

很简单的方式转换成数字使用PHP函数的话。

有没有简单的方法将数字转换为PHP中的单词？
