Here's a more basic tutorial for those who'd like to start from the beginning:
"The Zend Framework provides clean, stable code, complete with -- and perhaps most importantly -- clean intellectual property rights. PHP is gaining ground in the enterprise space, but if you're a Fortune 500 company, you don't want to take a chance on a module submitted to a repository that may or may not be some other company's intellectual property.
What is Zend Framework, exactly? The Zend Framework:
- Is based on PHP.
- Is object-oriented.
- Uses the MVC paradigm.
- Has open source contributors.
- Has contributors who take responsibility for the fact that their code is not the intellectual property of someone else.
