there’s this website and it has a Flash game. You can talk to your online opponent while the two of you are playing. how can this chat thing be done in a simple but very effective way and easy to understand??
Simple and easy to understand isn’t really an option here.
You will have to have an understanding of loadVars in Flash and PHP.
I do not have that knowledge, so I can not help you. Sorry 
To put it bluntly… lost is right in one aspect… it’s not simple…
You can achieve this in multiple different ways… I could tell you a way to make multiplayer games and a server off your computer… But it would take eons…
lol…
Basically… Search around and experiment… Try lower things… Then work your way up.
Peace<:}
Actually, the easiest way is to use the XML Object, you could search google.com, or check ‘Server-Side/Scripting’ forum.
Btw, you should install a socket server as well, Unity of Colin moock is a good one/ [link]
