I have that PHP & MySQL book in the second picture, with the nuts and bolts on it and orange behind the title. I really must say, do not try to learn much from that book. It uses some of the most insecure code I have ever seen, many SQL-injection / XSS issues in every project. Some of the concepts given in the book are decent, but the lack of any form of security makes it a dangerous book. I regret getting it, but at least it was a gift. Just wanted to give a heads up, but given your work on the Cabbit stuff, you're likely beyond this book in terms of knowledge.
