Instead of reading this book from front to back I read the sections as needed. PHP isn't the only language I dabble in so I haven't had many opportunities to go through the book but the sections I have read are very well written, informative and easy to read.
I would say this book could be utilized by a novice or experienced PHP programmer. The author covers topics starting advanced enough not to bore the hell out of the experienced and thorough enough not to loose the novice.
