The workshop is designed to help you anticipate possible questions, review what you've learned, and begin learning how to put your knowledge into practice.
1: | Which function would you use to start or resume a session? |
A1: | You can start a session by using the session_start() function. |
2: | Which function contains the current session's ID? |
A2: | You can access the session's ID by using the session_id() function. |
3: | How would you end a session and erase all traces of it for future visits? |
A3: | The session_destroy() function removes all traces of a session for future requests. |
4: | What does the SID constant return? |
A4: | 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.
