Once you set the Locale to the NumberFormatter, you can fetch the Currency Code with

$formatter = new NumberFormatter('de_DE', NumberFormatter::CURRENCY);
echo $formatter->getTextAttribute(NumberFormatter::CURRENCY_CODE);

$formatter = new NumberFormatter('ja_JP', NumberFormatter::CURRENCY);
echo $formatter->getTextAttribute(NumberFormatter::CURRENCY_CODE);
