I'm interested to find out what Stack Overflow believes the best PHP book is - both for those who are beginners to web programming as well as those who have previous programming experience (they don't have to be same book). "Best" includes being both reasonably up-to-date and encouraging best practices for secure, modern, PHP programming.
There seems to be a lot of books out there and unlike other languages there doesn't seem to be a single well-regarded book and it's hard to separate the wheat from the chaff, so I'm interested to see what the community believes is good - both for personal use and for future recommendation to others.
Thanks.
To clarify: I know of the PHP manual which is largely a reference, not paper, makes little comment as to proper style and is not what I'm looking for.
