很可能我完全不了解 Zend 处理货币的方法。
我想要做的是有一个 Zend_Currency 对象，其中活动货币为 EURO，语言为英语（应用程序的区域设置为 en_GB）。 Zend_Currency 连接到一个语言环境，如果用英语语言环境创建 Zend_Currency，我就不能有 EUR。
这个我也试过了
$this->currency = new Zend_Currency(array('currency' => 'EUR'), "en_GB");
但如果我尝试
echo $this->currency->getSymbol(); // I get £
而且没有更改货币的方法。

这行得通：
$this->currency = new Zend_Currency('en_GB');
$this->currency->setFormat(array('currency' => 'EUR', 'name' =>'EUR', 'symbol' => '€'));
【讨论】：
我扩展了Zend_Currency 并覆盖了getName() 和getSymbol() 方法，以便它们（当区域设置更改时Zend_Currency 也是如此，这是我们不想要的......）从@ 返回“新鲜”数据987654325@每次我提出请求。
在下面的示例类中，您可以创建Default_Model_Currency() 的实例并将“货币”选项设置为任何有效货币（例如欧元、美元等），同时保持相同的区域设置。

【讨论】：
这似乎可行：-
$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
