The PHP Developer's Network forums were abuzz today after a member's proposal to write a community PHP book for novice programmers, with sections targeting advanced topics and programmers. The instigator was d11wtq (Chris Corbyn), who on a side note recently released the excellent Swift Mailer library. It's a simple proposal - write a book, and release it in some (or many) formats for free.
So why write yet another PHP book? I think the proposal caught such attention because of the method of writing and the motivation for doing so. And admit it, it's a very intriguing idea.
He talks more about how the book would be created ("a community sourced effort") and how quality of the content would be maintained. Creative freedom would also be engouraged, and some motivations as to why a developer would want to contribute to the book at all.
