Magento - load local.xml based on the environment

I want to have 3 app/etc/local.xmlfiles - name them local.xml staging.xml and live.xml.

I want to load them based on an environment variable that I set in either vhosts or htaccess. This way, I can have separate databases, etc., but one code base that I can save under svn.

What would be the best way to achieve this?

local.xml hardcoded in multiple Magento files.

So, if you want to implement your own choice of file name for this, you will have to redefine a few basic classes / methods / functions accordingly.

local.xml * , , , /app/Mage.php. , Mage ( final).

, /app/Mage.php, Magento .

,

Mage_Core_Model_Config
Mage_Core_Model_Layout_Update

, ,

Mage_Install_Model_Installer_Config
Mage_Adminhtml_Block_Notification_Security (1.5.1)

.

, . :

class Mynamespace_Mymodule_Helper_Data extends Mage_Core_Helper_Data
{
    public function getLocalXMLFileName()
    {
        return getenv('MY_XML') . 'xml';
    }    
}

, .

$updateFiles[] = 'local.xml';


$updateFiles[] = Mage::helper('mymodule')->getLocalXMLFileName();
