Exercise 9-2
                  In this project, you will create a cookies program that stores the date
                  and time of a user’s last visit.
                     1.   Create a new document in your text editor and type the
                           declaration,  element, header information,
                          and  element. Use the strict DTD and “Last Visit” as
                          the content of the  element.
                     2.   Add the following script section above the 
                          declaration:
                          

                     3.   Add the following if...else statement to the script sec-
                          tion to assign a value to the $LastVisit variable. If the
                          $_COOKIE['lastVisit'] variable is set, the date and time of
                          the last visit is assigned to the $LastVisit variable. Otherwise,
                          the variable is assigned a value of “This is your first visit!”
                          if (isset($_COOKIE['lastVisit']))
                               $LastVisit = "Your last visit was on "
                                    . $_COOKIE['lastVisit'];
                          else
                               $LastVisit = "This is your first visit!\n";

                     4.   Add the following statement to the end of the script sec-
                          tion. The statement uses the date() function with the
                          setcookie() function to assign the date to the $LastVisit
                          variable. Notice that the cookie is set to expire in one year.
                          setcookie("lastVisit", date("F j, Y, g:i a"),
                               time()+60*60*24*365);

                     5.   To the document body, add the following output directive,
                          which displays the value of the $LastVisit variable:
                          

                     6.   Save the document as LastVisit.php in the Projects direc-
                          tory for Chapter 9, and then close the document in your text
                          editor.



 7.   Open the LastVisit.php file in your Web browser by enter-
        ing the following URL: http:///PHP_Projects/
        Chapter.09/Projects/LastVisit.php. The first time you open the
        page, you should see “This is your first visit!” in the browser
        window. Reload the Web page; you should see the date and
        time in the browser window.
                                                                           
   8.   Close your Web browser window.
