Zend Currency in Euro with English locale
It is very possible that I totally don't understand the Zend aproach in working with curr开发者_Python百科encies.
What I want to do is to have a Zend_Currency object where the active currency is EURO and the language to be English (the locale of the application is en_GB). Zend_Currency is connected to a locale and if a create a Zend_Currency with an English locale I cannot have EUR.
I've also tried this
$this->currency = new Zend_Currency(array('currency' => 'EUR'), "en_GB");
But if I try to
echo $this->currency->getSymbol(); // I get £
And there are no methods for changing the currency.
This worked:
$this->currency = new Zend_Currency('en_GB');
$this->currency->setFormat(array('currency' => 'EUR', 'name' =>'EUR', 'symbol' => '€'));
I have extended Zend_Currency
and overwritten the getName()
and getSymbol()
methods so that they (as does Zend_Currency
when the locale changed, which we don't want..) return 'fresh' data from Zend_Locale_Data
each time I do a request.
In the example class below you can create an instance of Default_Model_Currency()
and set the 'currency' option to any valid currency (eg. EUR, USD etc) while keeping the same locale.

This seems to work :-
$currency = new Zend_Currency();
$currency->setFormat(array('currency' => 'EUR', 'symbol' => '€'));
You can pass getFormat() an array to set the options like this. http://framework.zend.com/manual/en/zend.currency.options.html
