Constant support for Zend_Config_Xml

Tuesday, July 21, 2009

Today I added support for constants in Zend_Config_Xml. This new feature will be available in Zend Framework 1.9. It was added via a Zend_Config_Xml specific XML namespace. To give you an easy example of how that may work:
<config xmlns:zf="http://framework.zend.com/xml/zend-config-xml/1.0/">
    <production>
        <includePath><zf:const zf:name="APPLICATION_PATH"/>/library</includePath>
    </production>
</config>
On PHP side, it works like usual:
<?php
define('APPLICATION_PATH', dirname(__FILE__));
$config = new Zend_Config_Xml($xmlString, 'production');

echo $config->includePath; // Prints "/var/www/something/library"
Additionally, the "extends" attribute was also moved to this new namespace, making the NULL namespaced extends attribute deprecated until ZF 2.0, when it will be removed.

    Nice one! Does this also work for class constants like Foo::BAR?

    Nope, that only works for usual PHP constants, as in .ini config files.

    It's good tools. but for first code of bootstrap not good because XML file have so time for pars and need cache before use.
    But this way is useful.
