Client Side Cursor Vs Sever Side Cursor?

I having a difficult time here trying to figure out what to do here.
I need a way to scroll through a recordset and display the results
with both forward and backward movement on a web page(PHP using
ADO/COM)..

I know that if I use a client side cursor all the records get shoved
to the client everytime that stored procedure is executed..if this
database grows big wont that be an issue?..

I know that I can set up a server side cursor that will only send the
record I need to the front end but..

Ive been reading around and a lot of people have been saying never to
use a server side cursor because of peformance issues.

So i guess im weighing network performance needs with the client side
cursor vs server performance with the server side cursor..I am really
confused..which one should I use?
