On Vidyut Luther's blog today (phpcult.com), there's his brief review of a PHP-related book offered from SitePoint, No Nonsense XML Web Development With PHP.
This weekend, I had a chance to go out of town. Since, my laptop was in the shop, I was forced to go with just my Treo 650 and some books. I decided to take "No Nonsense XML Web Development With PHP" by Thomas Myer. I haven't finished the book yet, but after reading a few chapters, I felt it was worth other peoples time.
