The most scary thing is the author claims to be completely void of any theory or even ability to explain simple things ("explain something as simple as a nested array"?) one could learn in a day with quick look at a "learn whatever in 21 days"... but yet, he has published a technical book on PHP. Something smells in that story.
its for marketers...just explains VERY basic concepts...variables, if/then/else...things like that. Aimed at affiliate marketers who want to punch up their websites with a little PHP. I'd hardly call it a technical manual. And besides, I can explain things when I have reference material in front of me...but on the fly in an interview would be totally unable to.
