或者，您可以在PHP中使用intl包中的NumberFormatter类。这是一个示例代码，可以帮助您（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";

这是我今晚写的一个小班。注意事项：
longform方法不处理小数。它只是抹去了它们。如果您愿意，可以随意修改并添加该功能。 numberformat方法确实执行小数，但不执行任何舍入。由于PHP对整数大小的固有限制，我不得不创建一个新的numberformat函数。我翻译的数字太大，以至于当我使用number_format()检查我的翻译时，我花了30分钟才意识到我的翻译没有错，number_format是。 2,147,483,647的整数（20亿和更改）。 64位版本最多可以处理9 quintillion或类似内容。但只要您将数字作为longform提供给string方法，这就不相关了。只要我将ajax传递给服务器，我就可以从网络表单中获得一个超过''+number的306位数字。 因此，此类会将数字转换为999 Centillion, 999 etc.（例如，长度为9到306个字符的字符串）。任何大于此的数字，该函数只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，它在正确的位置尽可能地添加逗号，以使数字更具可读性。
顺便说一下，如果你希望它是负数，你可以在前面放一个-，但输入字符串中包含的任何其他字符都将被删除。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
任何其他方法都不需要numberformat方法。如果您想检查一个非常长的翻译号码，它就在那里。由于所有这些函数都将数字作为字符串处理，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当我记不起十亿分之后的事情时，我正在看的网站上的最后一个数字。

是的。无需使用库，您只需遵循此步骤即可。
首先，您需要在服务器中检入 php.ini 中的;extension=php_intl.dll是否启用，如果仍然无法正常工作，则需要查看此答案。
intl extension php_intl.dll with wamp
成功移动所有文件后，以 icu 开头。
来自：<wamp_installation_path>/bin/php/php5.4.3/
收件人：<wamp_installation_path>/bin/apache/apache2.2.22/bin/
然后重新启动服务器。
尝试运行以下代码：
$f = new NumberFormatter("en", NumberFormatter::SPELLOUT);
echo $f->format(123456);
它将显示 123.5465 的输出。
