Much of this book's material can be found just as easily and for free in the documentation that comes with CodeIgniter. Some of the material in the second half of the book was useful to me, though it was offset to a large extent by some iffy material, including what to me appeared to be some rather poor implementation of OOP concepts. This book may be useful to intermediate PHP developers who are brand new to CodeIgniter, but I cannot recommend it to anyone with more experience with both.
