I\'m interested in using Doctrine as an ORM for a new Zend Framework app I\'m writing. I\'m trying to figure out the best way to integrate it as straightforward as possible.
As far as auto-loading is concerned, you can actually use the Doctrine loader with the new Zend_Loader_Autoloader stack quite easily. Take a look at this page, especially where it mentions the pushAutoloader() method.
Here's the basic run down, though:
$autoloader = Zend_Loader_Autoloader->getInstance();
$autoloader->pushAutoloader(array('Doctrine', 'autoload'), 'Doctrine');
This will use Doctrine's own autoloader for only classes that begin with Doctrine, if they are not already found by other autoloaders in the stack.
Hope this helps a bit.
