Tips on what?
If you need a tutorial or source to learn from, I recommend taking a look at
[Only registered and activated users can see links. Click Here To Register...] and choosing any site you feel comfortable with.
If you want mor information on where to start when making a browser game... well, I guess that's rather experience than something you can just learn from a book.
I would of course recommend taking a look at my own creation: SHPS (link in signature). It should give you all the basic stuff you need (like user management) and you can fill it with your content and focus on the client side.
If you rather use some fancy MVC framework or something you are very familiar with and don't want to miss, I recommend starting with simple templating and just making the pages you need without any functionalities. Then, in a second step, you can add the code (registration/login, database manipulation, game functionalities,...). At least, that's what I would do.
Don't implement everything you want to see in your game. Just code the basic functionalities. When done, open it up for people and keep adding content. That will keep you motivated and also word about your game will spread even while you are still developing it.
