How to integrate cakephp with wordpress.???
It rather depends what you're looking to do - doesn't it.
Simply i want to add CMS into Framework.
I've built an MVC framework within WordPress before, and I've seen tutorials showing how to integrate an existing MVC framework into WordPress (the one I saw was using Yii) through the creation of a bespoke WordPress plugin.
There are a couple of ways to do it. One is to add rewrite rules for your framework to the WP .htaccess file, or alternatively, you can use WP Rewrite to dispatch requests to the framework internally. The latter provides a more seamless approach.
Something you might find interesting is WP MVC.
Alternatively, a quick Google revealed this too.
