Yes it should be as long as you call session_start() in each page

In each page meaning in each PHP file ?

@Cygnus no, you need to call
session_start() once per request. The best way is to put it in your entry point (i.e. index.php or a config.php that gets included for every request). After that all files you include (during the same request) will be able to access your session variables.

It depends if you are using a framework etc. If you are using just plain PHP with no framework (and therefore no page that is included every request), you will need to include every page. The example on the PHP manual i sent explains.

@AndrewHall : I read that. Im still facing problem in my code though. I have a GetData.php file the script in which will be executed (it sets the session variables) when page client_show.php loads. Now, im using AJAX to retrieve data from another PHP file on a user action. In that other file, i have to access the variables set by GetData.php. But when i do, the session variable is turning up as empty.

OK, there seems to be some other problem altogether. In the file in which i'm accessing the session variable ( set in another file ), it says Undefined variable $_SESSION. Any hints on what could be wrong ?
