hymanroth: I was in the exactly the same situation as you. Learn PHP first because it will give you the logical framework for understanding how the web server interacts with the browser. I recommend Rasmus' book: http://www.amazon.com/Programming-PHP-Rasmus-Lerdorf/dp/1565... - it's the best text book I've ever read: he gives you exactly the right amount of detail.Later you can pick-up Javascript. There are loads of resources for this, but learn PHP first.
