zend currency negative sign - zend-framework

Question

Hello i am using Zend_currency
class Currency extends Zend_View_Helper_Abstract
{
public function currency($number, $locale = 'it_IT') {
$currency = new Zend_Currency($locale);
$number = $number + 0.00;//convert to float
return $currency->toCurrency((float) $number);
}
}
in a some view .phtml file
echo $this->currency($gimme_my_money);
and this is what i get
€ 19.373,25
-€ 116,07
how can i get it to print negative numbers like
€ -116,07

Answer 1

Just overwrite the format option like this:
$cur = new Zend_Currency(array('format' => '¤ #,##0.00;¤ -#,##0.00'));
The trick is in the second part of the string (after the comma), I've checked it for Italian locale and the format string provided there is ¤ #,##0.00.
This is tested with ZF 1.11.7

Answer 2

I don't think this formatting option is built into Zend_Currency.
What you can do, is move the currency symbol to the right side:
$this->view->total = new Zend_Currency(array('value' => $total, 'position' => Zend_Currency::RIGHT));
And then your currencies will be displayed with the currency symbol on the right:
-19.373,25 €
If you want a custom formatting, with the negative sign after the symbol, (€ -116,07), you will have to write your own currency formatter or built on top of Zend_Currency

try this:
class My_View_Helper_Currency extends Zend_View_Helper_Abstract
{
/**
* Format a numeric currency value and return it as a string
*
* #param int|float $value any value that return true with is_numeric
* #param array $options additional options to pass to the currency
* constructor
* #param string $locale locale value
*
* #throws InvalidParameterException if the $value parameter is not numeric
* #return string the formatted value
*/
public function currency($value, $options = array(), $locale = null)
{
if (!is_numeric($value)) {
throw new InvalidArgumentException(
'Numeric argument expected ' . gettype($value) . ' given'
);
}
$options = array_merge($options, array('value' => $value));
$currency = new Zend_Currency($options, $locale);
return $currency->toString();
}
}
