This issue has been moved from the zendframework repository as part of the bug migration program as outlined here - http://framework.zend.com/blog/2016-04-11-issue-closures.html

Original Issue: https://github.com/zendframework/zendframework/issues/6852 User: @Gawel1 Created On: 2014-11-07T11:02:04Z Updated At: 2014-11-17T15:06:04Z Body Apply comment visible in http://php.net/manual/en/numberformatter.formatcurrency.php :

When you want to format currency's without sub units and the currency is not the one used by the given locale you need to set the currency code before as TextAttribute BEFORE setting the NumberFormatter::FRACTION_DIGITS

$fmt = new NumberFormatter('en_US', NumberFormatter::CURRENCY);
$fmt->setTextAttribute(NumberFormatter::CURRENCY_CODE, 'EUR');
$fmt->setAttribute(NumberFormatter::FRACTION_DIGITS, 0);
$fmt->formatCurrency(100, 'EUR');
