I like the Dummies books.
OK, so I'm not sophisticated, professional, or even very smart. But so many computer books seem to forget the first twenty pages that explain just what the hell you are trying to do. Perhaps the Dummies books take 40 pages to explain what could have been donw in 20, but that's not a problem. I can read fast.
It has often happened that I first read a Dummies book and then once I'm deep into doing something with that language I need to go get a more complete Bible type book. I haven't gotten far enough into PHP yet to know if this is true, but in moving a web site over to Unix (BSD), Postgre, Apache, and PHP; I don't have the time to read a Bible on each one of these. This book, along with some other Dummies books is getting me started a lot faster than I thought possible.
