Zend_Pagination adapter for Propel
Like recently proposed by Jason Eisenmenger, I’ve written a Zend_Pagination adapter for Propel.
It uses the DbFinder symfony plugin (formerly sfPropelFinder) which mimics Doctrine’s way of performing queries. The strictlyPHP_Propel_Finder used below is just a wrapper around that plugin.
Please note: it can certainly be improved (and I’m not sure the Zend Framework coding standards are met).
