quick question, Im starting to develop the backend for a Flash game, and Im very used to AS3 sintax, and I know that Java has a very similar sintaxis, in the other hand I heard that it could be a little more complex to do than with php.
So, Im kind of new to php, and I could get used very quickly to Java, whats my best option?
(I need to do things like: user login, highscore table, etc)
It depends on the complexity that you have in the server side. Usually a Flash game do not need a complex business logic in the server side, I would use PHP in this case, Java otherwise.
If you are going to host this application, Java hosts are way more expensive than PHP ones also.
