Zend Framework is a big & heavy object-oriented framework for PHP. I started working with ZF a couple of months ago, I liked it's documention (it's very well documented) and decided to stick with this framework. Here is the latest version of the framework '" at the time of writing v1.6.1.
He talks about the framework's use of the MVC pattern, its coding standards, and some of the basic terms and file structure behind a simple ZF application. He's even included an .htaccess file and a sample bootstrap (index.php) to get you started.
