Upcoming wrox php/flash book?

I was searching for a Flash book today and ran across the following book, due to be released in September 2001: http://shop.barnesandnoble.com/bookSearch/isbnInquiry.asp?isbn=190345016 0 It's entitled "Foundation Php for Flash 5" Now, I've never heard of using PHP to control Flash and, given the different ways they work, can't see how it would even be possible. (I'm no flash expert, but I believe they have to be pre-compiled .swf files to be displayed in a web page.) Wrox.com has no mention of this book in their upcoming releases section and google didn't turn up any hits, either. (Amazon doesn't have the book listed in their DB) Does anyone know any more about this book (and what PHP is going to be doing with Flash?)? I'm more inclined to believe someone over at Barnes & Noble goofed, but stranger things have happened. --kurt
