should I use php or javascript or both

[boballoo]

I would like to develop my own context ad application similar to http://www.kontera.com/demo.aspx, but I am not a programmer and do not know where to start. All the ones I have seen so far use JavaScript, but I would like a professional opinion as to whether this is the best programming language to use for this type of thing. But there is a definite need for a database here so maybe I should use PHP in conjunction with JavaScript. (Please don't laugh, I am not new at running web businesses, but I know nothing about programming.) I thought this would be a good place to find out, but perhaps there might be some bias here. Anyway, I am open to all suggestions and comments from those who love JavaScript AND those who hate it as well as those who love PHP AND those who hate it. (Is there anyone who hates PHP?)

Both. Javascript just does the client side stuff, which makes deploying on a website very easy. There is plenty of server-side code too, which javascript would probably be calling that would be where you'd use perl or php, etc.
