Get currency symbol in PHP
提问by umpirsky
Let's start with simple piece of code to format money with NumberFormatter:
让我们从一段简单的代码开始，用以下代码格式化钱NumberFormatter：
$formatter = new NumberFormatter('en_US', NumberFormatter::CURRENCY);
echo $formatter->formatCurrency(123456789, 'JPY');
This prints: ￥123,456,789.
这打印：￥123,456,789。
This is ok if you want to format money.
如果你想格式化钱，这没问题。
But what I want to do is to get currency symbol (e.g. ￥) for given currency ISO 4217 code (e.g. JPY).
但我想要做的是获取给定货币 ISO 4217 代码（例如 JPY）的货币符号（例如 ￥）。
My first guess was to try using:
我的第一个猜测是尝试使用：
$formatter->getSymbol(NumberFormatter::CURRENCY_SYMBOL);
But that gives currency symbol for locale given in constructor (en_US), $ in my case.
但这给出了构造函数（en_US）中给出的语言环境的货币符号，在我的情况下为 $ 。
Is there a way to get currency symbol by currency ISO 4217 code in PHP?
有没有办法在 PHP 中通过货币 ISO 4217 代码获取货币符号？

I achieved this using https://github.com/symfony/Intl:
我使用https://github.com/symfony/Intl实现了这一点：
Symfony\Component\Intl\Intl::getCurrencyBundle()->getCurrencySymbol('EUR')

First of all, there is no international global currency symbol table, that anyone on the planet could read and understand.
首先，没有任何地球上任何人都可以阅读和理解的国际全球货币符号表。
In each region/country the currency symbols will differ, that`s why you must determine them based on who is reading, using the browser / user locale.
在每个地区/国家，货币符号会有所不同，这就是为什么您必须根据谁在阅读，使用浏览器/用户区域设置来确定它们。
The correct way is as you guessed, using NumberFormatter::CURRENCY_SYMBOL, but you first have to set the appropriate locale like en-US@currency=JPY:
正确的方法如您所料，使用 NumberFormatter::CURRENCY_SYMBOL，但您首先必须设置适当的语言环境，如en-US@currency=JPY：
$locale='en-US'; //browser or user locale
$currency='JPY';
$fmt = new NumberFormatter( $locale."@currency=$currency", NumberFormatter::CURRENCY );
$symbol = $fmt->getSymbol(NumberFormatter::CURRENCY_SYMBOL);
header("Content-Type: text/html; charset=UTF-8;");
echo $symbol;
This way the symbol will be understandable by the user.
这样，用户就可以理解符号。
For example, $symbol will be:
例如，$symbol 将是：
- Canadian dollar(CAD) : CA$in USA, CADin Romania , $CAin Iran
- Iran Rial(IRR): IRRin USA, while in Iran will be ?
- 加元（CAD）：CA $在美国，CAD在罗马尼亚，$ CA在伊朗
- 伊朗里亚尔(IRR)：美国的IRR，而伊朗将是?

If you set the locale using this function setlocale("LC_ALL", "es_AR");You can use localeconv()['currency_symbol']or localeconv()['int_curr_symbol']to get the locale currency symbol and the international variation of the currency symbol.
如果您使用此函数设置区域设置setlocale("LC_ALL", "es_AR");您可以使用localeconv()['currency_symbol']或localeconv()['int_curr_symbol']来获取区域设置货币符号和货币符号的国际变体。

Since the symbols can be multi-byte I used mb_*() functions to correctly grab the all non-punctuation and non-digit chars which would just leaves the symbol.
由于符号可以是多字节的，我使用 mb_*() 函数来正确抓取所有只会留下符号的非标点符号和非数字字符。
function get_currency_symbol($string)
{
$symbol = '';
$length = mb_strlen($string, 'utf-8');
for ($i = 0; $i < $length; $i++)
{
$char = mb_substr($string, $i, 1, 'utf-8');
if (!ctype_digit($char) && !ctype_punct($char))
$symbol .= $char;
}
return $symbol;
}
$format = new NumberFormatter('en_US', NumberFormatter::CURRENCY);
$string = $format->formatCurrency(123456789, 'JPY');
echo get_currency_symbol($string);

Cryptic has a good answer, but there is a simpler way to do it:
Cryptic 有一个很好的答案，但有一个更简单的方法：
preg_replace('#[a-z0-9.]*#i', '', $formatter->formatCurrency('0', $currency))
This is a nice simple inline solution that doesn't require declaring another function, however it also doesn't properly handle all cases - i.e. currencies where letters are part of the output. But for distinguishing between e.g. $ and ￡, it works fine.
这是一个很好的简单内联解决方案，不需要声明另一个函数，但是它也不能正确处理所有情况 - 即字母是输出一部分的货币。但是为了区分例如 $ 和 ￡，它工作正常。

You can use Symfony IntlComponent
您可以使用Symfony 国际组件
Install it via composer using composer require symfony/intl
使用 Composer 安装它 composer require symfony/intl
Then get the HTML symbol with the following
然后使用以下内容获取 HTML 符号
use Symfony\Component\Intl\Currencies;
\Locale::setDefault('en');
$symbol = Currencies::getSymbol('INR'); // => '?'
echo $symbol;

Zend_Locale::getTranslationList('CurrencySymbol')
Will give you an associative array of 3 letter currency codes to their symbol.
将为您提供一个由 3 个字母货币代码组成的关联数组与其符号。
Can then use like this:
然后可以这样使用：
$curArr = Zend_Locale::getTranslationList('CurrencySymbol');
echo $curArr['GBP'];

Try this variant:
试试这个变体：
$formatter->getSymbol(NumberFormatter::INTL_CURRENCY_SYMBOL);
