zend-framework - Zend 欧元货币，英语语言环境

Question

我很可能完全不理解 Zend 处理货币的方法。

我想要做的是有一个 Zend_Currency 对象，其中活动货币是 EURO，语言是英语（应用程序的语言环境是 en_GB）。Zend_Currency 连接到一个语言环境，如果创建一个带有英语语言环境的 Zend_Currency，我就不能有 EUR。

我也试过这个

$this->currency = new Zend_Currency(array('currency' => 'EUR'), "en_GB");

但如果我尝试

echo $this->currency->getSymbol(); // I get £

并且没有改变货币的方法。

Answer 1

这有效：

$this->currency = new Zend_Currency('en_GB');
$this->currency->setFormat(array('currency' =>  'EUR', 'name' =>'EUR', 'symbol' => '€'));

Answer 2

我已经扩展Zend_Currency并覆盖了getName()andgetSymbol()方法，以便它们（就像Zend_Currency我们不想要的语言环境更改时一样......）Zend_Locale_Data每次我发出请求时都返回“新鲜”数据。

在下面的示例类中，您可以创建一个实例Default_Model_Currency()并将“货币”选项设置为任何有效货币（例如欧元、美元等），同时保持相同的语言环境。

Answer 3

这似乎有效：-

$currency = new Zend_Currency();
$currency->setFormat(array('currency' => 'EUR', 'symbol' => '€'));

您可以传递 getFormat() 一个数组来设置这样的选项。 http://framework.zend.com/manual/en/zend.currency.options.html
