I was wondering if anyone knew how to use some components of the Zend Framework without having to actually use the framework. For example, I would like to use their Zend_Va
Zend framework components while being loosely couple are still coupled. If you would to use Zend_Mail component for example - that would actually also require:
Zend_Validation will be loaded for the mere reason of validating email address domain.
So - best bet would be to include entire Zend library. By pulling only several components - you'll soon end up in "dependency hell" especially as API changes (though that doesn't happen too often).
Also - starting from version 2.0 you must use some auto-loader to load Zend components as all require calls will be removed from PHP classes.
