On her Oracle blog today, Alison Holloway hints that a new version of the Undergorund PHP and Oracle Manual should be coming soon:
If you hadn't worked it out from this blog, I'm working on version 1.3 of The Underground PHP and Oracle Manual. So in a long and roundabout way what I'm really saying is stay tuned for more news on the upcoming release of the new and improved version of this book.
Unfortunately, her editor of choice (Word) has given her some problems and is delaying things a bit. Now all she needs is to "get the bookmarks and links working from a Word master document to Acrobat". Until then, you can check out the latest version here [pdf].
