On CodeSnipers.com today, there's a new book review posted of the APress book "Beginning Ajax with PHP" by Lee Babin.
Although no stranger to Ajax, I received a review copy of Beginning Ajax with PHP expecting some watered down presentation of Javascript with some PHP thrown in. I was quite surprised to find a good presentation of using Ajax and PHP, easy enough for the beginner and still interesting for those who have done it for years.
Nola covers the contents of the book, generalizing the sections just to give you a brief overview of what's going on in each chapter. She also describes the end of the book as a "random splattering of interesting topics" dealing with using Ajax in different, useful situations.
