Ken Guest has posted a book review today of an offering from Packt Publishing, Learning Facebook Application Development (by Hasin Hayder and Dr Mark Alexander Bain).

The book was published prior to Facebook's facelift but this doesn't really impact on the usefulness of the book. An overview of FBML, FQL, FBJS (a restricted subset of JavaScript and enforced for security reasons) are given along with information on how to use the test consoles, publish to news feeds, some multimedia aspects of what can be done in Facebook applications and more.

He notes that the book focuses on a PHP5-only world for developing the apps and opts for MySQL as the database of choice. Overall, he found it useful - more so than the online documentation, especially for beginners.
