A Kickstarter project has been started up by Alan Forbes to author a book (and full training course) to "bring the joy back" into learning PHP - The Joy of PHP Programming (e-book and course).
PHP is a great programming language. It's free, powerful, relatively easy to setup and learn, and it has extensions and frameworks available to do almost anything you could imagine. Frankly, it's just plain fun too. But if you've never programmed before or have programmed before but not with PHP and want to learn it, wouldn't it be great to find a tutorial that conveyed the sheer joy of it? That's what I want to do!
It plans to be an introductory book, starting developers from the ground up to teach them things like basic usage, project organization, working with user input and bits on frontend and backend frameworks. There's already over 150 backers for the project and just 20 days remaining so if you're interested in learning more about it or want to contribute, check out this page on Kickstarter.com.
