So many jobs these days are calling for Object Oriented PHP and I have been using PHP for almost 8 years but all procedural. I've used PEAR but not developing my own OOP skills. Also, been using eclipse IDE for PHP for 5 years

Several questions:
- How would one best learn OOP in PHP?

- Is Zend framework free for developers? Where do you get it? Is it worth it?

- What are the skills on top of PHP/MySQL that help you get jobs?

Thanks
