Use environment variables in your Magento local.xml configuration file

Ability to use envvars in Magento config

In our development workflow, our webservers provide environment configuration information to our applications via environment variables (i.e. MAGE_DB_HOST, MAGE_DB_USER etc). This doesn't sit well with Magento's XML based configuration approach.

This little hack allows us to use '$MAGE_DB_HOST' and any other environment variables in our XML configuration files.

Usage

Example part of our local.xml...

...
            <default_setup>
                <connection>
                    <host>$MAGE_DB_HOST</host>
                    <username>$MAGE_DB_USER</username>
                    <password>$MAGE_DB_PASS</password>
                    <dbname>$MAGE_DB_NAME</dbname>
                    <initStatements><![CDATA[SET NAMES utf8]]></initStatements>
                    <model><![CDATA[mysql4]]></model>
                    <type><![CDATA[pdo_mysql]]></type>
                    <pdoType></pdoType>
                    <active>1</active>
                </connection>
