PHP NumberFormatter打印ISO 3货币代码

Question

Is there any way to retrieve a notation of the currency like the following with the PHP NumberFormatter class:

100,00 EUR

Basically instead of the symbol € I want the ISO 3 code.

The alternative would be to omit the symbol completely, but I still want to keep the type as NumberFormatter:CURRENCY. Don't know how to do this either.

Is it about str_replace in the end?

You can set manually the currency symbol, with

$nf->setSymbol(\NumberFormatter::CURRENCY_SYMBOL, '<my symbol>');

& then use the format() method for formatting. But i think, that's not what you want. For example:

$nf_en = new \NumberFormatter('en', \NumberFormatter::CURRENCY);
$nf_en->setTextAttribute(\NumberFormatter::CURRENCY_CODE, 'EUR');
$nf_en->setSymbol(\NumberFormatter::CURRENCY_SYMBOL, 'EUR');

$nf_de = new \NumberFormatter('de', \NumberFormatter::CURRENCY);
$nf_de->setTextAttribute(\NumberFormatter::CURRENCY_CODE, 'EUR');
$nf_de->setSymbol(\NumberFormatter::CURRENCY_SYMBOL, 'EUR');

echo $nf_en->format(1); // this will print 'EUR1.00'!
echo $nf_de->format(1); // this will print 'EUR 1,00'!

If you set the currency code to '', still there will be locales, where the formatted strings will start (or end) with white space(s). It would be easier to use the NumberFormatter to format as a decimal number.
