PHP is definately the easiest to learn and the most efficient to code for this business, in my opinion. I can make a scraper, site gen or whatever in an hour or less with full db support and error checking. Can't do that in many other languages.
Java has a ton of potential but until you start running teams of people and need to get into the corporate sector this won't suit you that well.
If you want to get really heavy duty Python has some very nice threading capabilities. But you can always call it from PHP.
