.13 => ''$' . number_format($money, 2);
.13'
.1 => 'echo money_format('$%i', 3.4); // echos '.40'
.10'
0 => ' $number = "123.45";
$formatter = new NumberFormatter('en_US', NumberFormatter::CURRENCY);

PHP also has money_format().
PHP 也有money_format()。
Here's an example:
下面是一个例子：
printf("$%01.2f", $money);
This function actually has tons of options, go to the documentation I linked to to see them.
这个功能实际上有很多选项，去我链接的文档中查看它们。
Note: money_format is undefined in Windows.
注意：money_format 在 Windows 中是未定义的。
UPDATE: Via the PHP manual: https://www.php.net/manual/en/function.money-format.php
更新：通过 PHP 手册：https: //www.php.net/manual/en/function.money-format.php
WARNING: This function [money_format] has been DEPRECATED as of PHP 7.4.0. Relying on this function is highly discouraged.
警告：从 PHP 7.4.0 开始，此函数 [ money_format] 已被弃用。强烈建议不要依赖此功能。
Instead, look into NumberFormatter::formatCurrency.
相反，请查看NumberFormatter::formatCurrency。
$f = new NumberFormatter("en", NumberFormatter::CURRENCY);
$f->formatCurrency(12345, "USD"); // Outputs ",345.00"

i tried money_format()but it didn't work for me at all. then i tried the following one. it worked perfect for me. hopefully it will work in right way for you too.. :)
我试过了， money_format()但它根本不适合我。然后我尝试了以下一个。它对我来说很完美。希望它也能以正确的方式为您工作.. :)
you should use this one
你应该用这个
'$' . number_format($money, 2);
it will show money number in terms of money format up to 2 decimal.
它将以货币格式显示货币编号，最多为 2 位小数。

Note that in PHP 7.4, money_format() function is deprecated. It can be replaced by the intl NumberFormatter functionality, just make sure you enable the php-intl extension. It's a small amount of effort and worth it as you get a lot of customizability.
请注意，在 PHP 7.4 中，money_format() 函数已弃用。它可以被 intl NumberFormatter 功能取代，只要确保你启用了 php-intl 扩展。这是少量的努力并且值得，因为您可以获得很多可定制性。
$amount = 123.456;
// for Canadian Dollars
$currency = 'CAD';
// for Canadian English
$locale = 'en_CA';
$fmt = new \NumberFormatter( $locale, \NumberFormatter::CURRENCY );
echo $fmt->formatCurrency($amount, $currency);
The fast way that will still work for 7.4 is as mentioned by Darryl Hein:
Darryl Hein提到了仍然适用于 7.4 的快速方法：
/* Just Do the following, */
echo money_format("%(#10n","123.45"); //Output $ 123.45
/* If Negative Number -123.45 */
echo money_format("%(#10n","-123.45"); //Output ($ 123.45)
