PHP：用文字表达数字

PHP: Express Number in Words

提问by anita.kcx

Is there a function that will express any given number in words?

有没有一个函数可以用文字表达任何给定的数字？

For example:

例如：

If a number is 1432, then this function will return "One thousand four hundred and thirty two".

如果数字是1432，则此函数将返回“一千四百三十二”。

Use the NumberFormatter classthat are in php ;)

使用php 中的NumberFormatter 类；)

$f = new NumberFormatter("en", NumberFormatter::SPELLOUT);
echo $f->format(1432);

That would output "one thousand four hundred thirty-two"

那将输出“一千四百三十二”

You can do this in many ways I am mentioning here two ways by using The NumberFormatter classas mentioned in Martindillinganswer (if you have php version 5.3.0 or higher and also PECL extension 1.0.0 or higher) or by using the following custom function.

您可以通过使用Martindilling回答中提到的 NumberFormatter 类（如果您有 php 版本 5.3.0 或更高版本以及 PECL 扩展 1.0.0 或更高版本）或使用以下自定义功能。

function convertNumberToWord($num = false)
{
    $num = str_replace(array(',', ' '), '' , trim($num));
    if(! $num) {
        return false;
    }
    $num = (int) $num;
    $words = array();
    $list1 = array('', 'one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten', 'eleven',
        'twelve', 'thirteen', 'fourteen', 'fifteen', 'sixteen', 'seventeen', 'eighteen', 'nineteen'
    );
    $list2 = array('', 'ten', 'twenty', 'thirty', 'forty', 'fifty', 'sixty', 'seventy', 'eighty', 'ninety', 'hundred');
    $list3 = array('', 'thousand', 'million', 'billion', 'trillion', 'quadrillion', 'quintillion', 'sextillion', 'septillion',
        'octillion', 'nonillion', 'decillion', 'undecillion', 'duodecillion', 'tredecillion', 'quattuordecillion',
        'quindecillion', 'sexdecillion', 'septendecillion', 'octodecillion', 'novemdecillion', 'vigintillion'
    );
    $num_length = strlen($num);
    $levels = (int) (($num_length + 2) / 3);
    $max_length = $levels * 3;
    $num = substr('00' . $num, -$max_length);
    $num_levels = str_split($num, 3);
    for ($i = 0; $i < count($num_levels); $i++) {
        $levels--;
        $hundreds = (int) ($num_levels[$i] / 100);
        $hundreds = ($hundreds ? ' ' . $list1[$hundreds] . ' hundred' . ' ' : '');
        $tens = (int) ($num_levels[$i] % 100);
        $singles = '';
        if ( $tens < 20 ) {
            $tens = ($tens ? ' ' . $list1[$tens] . ' ' : '' );
        } else {
            $tens = (int)($tens / 10);
            $tens = ' ' . $list2[$tens] . ' ';
            $singles = (int) ($num_levels[$i] % 10);
            $singles = ' ' . $list1[$singles] . ' ';
        }
        $words[] = $hundreds . $tens . $singles . ( ( $levels && ( int ) ( $num_levels[$i] ) ) ? ' ' . $list3[$levels] . ' ' : '' );
    } //end for loop
    $commas = count($words);
    if ($commas > 1) {
        $commas = $commas - 1;
    }
    return implode(' ', $words);
}

In case of using Yii2 you can do this as simple as the following:

在使用 Yii2 的情况下，您可以简单地执行以下操作：

$sum = 100500;
echo Yii::$app->formatter->asSpellout($sum);

This prints spelled out $sumin your app's language.

这会打印出$sum以您的应用程序语言拼写的内容。
