Review title: This book needed an editor.
Product review: The book would explain PHP well if there weren't so many grammatical errors. The first few chapters were well worth reading, but about halfway through, stilted sentences and the incorrect use of "which" and "that" put me off the treatise entirely. I know that books of this ilk must be written hurriedly so the technology described in the book doesn't get a chance to change substantially before the book goes to market, but this is ridiculous. If I were shopping for a PHP book, I'd look seriously at some others.
