Greatest. CakePHP. Series. Ever.
Just in case you haven’t noticed yet, on CakepPHP’s Core Developer Jose Diaz Gonzales’ Blog, there is the CakeAdvent: from December 1st, one post each day, a great collection of advanced topics and tips. At the moment of this writing, I suppose there are still 11 posts to go.
If you use CakePHP, it’s a must read. If you plan using it, a must read too – after the official documentation and tutorials.
