"This book assumes only a basic knowledge of HTML, although the more comfortable you are handling raw HTML code w/o the aid of WYSIWYG, the easier the transition to using PHP will be. [...] Previous programming experience is not required. However, it may expedite your learning."
-Intro page #16
Oh, how I wish they would take to writing this on the cover of every "how to" computer text. It certainly would save everyone from guessing which book best suits their skill level, and possibly buying a book over their head, under their skill or completely off-topic.
I had to wade through 16 pages of introduction to find this gem, which would be so much more useful to know straightaway, in the bookstore! Alas, I cannot speak on this statement's accuracy... yet! But as my novice PHP brain slowly absorbs it's texty goodness, I will let you know exactly how 'basic' this book assumes I am.
