Other wise u use hidden values or cookie

[maheswaran]

else you can write these values into files (like txt ) and read the values from these files when you need this......

You could also use a database, althought that might be a bit extreme. Sessions is the best way to accomplish this.

Hi
This job can be done in many ways BUT the fastest and most secure way is to store a session on the server.

Other options:
1- Putting user information in a file. This way will overload the server and crash the systems if you have many users AND the other thing as that for doing this you have to have some information sent by user on each page just like a SESSION ID. It could be a cookie or a hidden object on each page . (This way is not recommended at all)

2- putting users information on a database. This way is faster than the first one but you still need to get an ID from user on each page to identify him/her. or you can save their IP address on the same database. What's wrong with this method? The first problem is that you have to send and recieve data from your database on each page. And the other problem is that some internet providers change the users IP on each page they view. That means your data will be lost and users will need to log in on each page. (This way is not recommended)

3- The 3rd way I can think of is to sore a Cookie on the users machine. This way is actualy faster than SESSION because the variables will be stored on the users computer not our server. But the problem is that people are able to easily change cookies. So lets use them for other things like (page language) , (users custom background color) , etc

4- The last and the worst way I can think of is to send users information with URL. NOT SECURE AT ALL. Because even if you encrypt the data anyone can copy the URL and login with your name. (DONT EVEN THINK ABOUT IT)


Why do we have to use session?
1- Because login informations are stored on the server and user can NOT reach them.
2- They are deleted after a period of not using them.
3- It's faster than most of other ways.
