Answer 2

或者,您可以使用intlPHP中的包中的NumberFormatter类.这是一个示例代码,可以帮助您入门(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"; 
    }

Answer 4

使用 NumberFormatter 类可以很简单地转换为单词。

<?php

$number = '12345';
$locale = 'en_US';
$fmt = numfmt_create($locale, NumberFormatter::SPELLOUT);
$in_words = numfmt_format($fmt, $number);

print_r($in_words);
// twelve thousand three hundred forty-five

?>

Answer 5

我需要一个解决方案，将 'and' 放入返回的字符串中并将其格式化为一个句子 - 通常就像人类所说的那样。所以我稍微调整了一个不同的解决方案 - 发布是因为我认为这对某人有用。

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

代码
