We can get the value of current session with the use of session_id() returns the session id for the current session.

Apart from session_id, we can retrieve it using SID constant in PHP6.

Also look at : PHP-sessions

Hope this helps.

You might want to check the php manual for session id. There are links to related functions as well :)

To see all available SESSION I use the following code:

foreach($_SESSION as $k=>$v)
   echo "$k=>$v<br/>";

Above code will be helpful when you are working with lots of SESSION variables.
