I prefer to reduce SESSION usage as much as possible. but I dont hesitate to use them if need arises. Points to note - Execution time: Only session_id is stored on the client's computer, and the actual data is stored on the server. so it will take nearly same time to process 100 session vars and 1 session var. - Security: While passing data trough hidden form fields, it is easy for the user to be change it. but its impossible (the user can change the session_id though) for the user to change the data stored in a session. - register_globals: i always set this off. but my host turned this on. had to spend 2 full days to find out what the problem was. coming back to you issue: IMHO storing stuff like" MaxDisplayRecords, DefaultDisplayRecords, etc.," in a SESSION var is the best solution. alternatives being - Hidden fields: this will add to unnecessary network traffic. - Use separate file: Why use a separate file if PHP does the job for you? - Use the database: If you have an existing connection this is OK. But this will become a bottle neck if u dont have an existing connection
