Which function would you use to start or resume a session?

Which function contains the current session's ID?

How would you end a session and erase all traces of it for future visits?

What does the SID constant return?

You can start a session by using the session_start() function.

You can access the session's ID by using the session_id() function.

The session_destroy() function removes all traces of a session for future requests.

If cookies are not available, the SID constant contains a name/value pair that can be incorporated in a query string. It will pass the session ID from script request to script request.

Create a script that uses session functions to remember which pages in your environment the user has visited. Provide the user with a list of links on each page to make it easy for her to retrace her steps.
