This script expects to be passed a memberId query string parameter specifying the member to be
displayed. This value is then passed to Member::getMember() to retrieve the record as a Member object.
If nothing is returned from the call to getMember() , the member could not be found in the members
table, so an error message is displayed and the script exits.
Assuming the member was found and retrieved, the script then calls LogEntry::getLogEntries() ,
again passing in the member ID, in order to retrieve the rows in the accessLog table associated with
this member (if any).
Next, the script displays all of the member fields inside an HTML definition list ( dl ) element. Mostly this
is simply a case of calling Member::getValueEncoded() for each field, passing in the name of the field
to retrieve, and displaying the returned value. For the special cases of gender and favorite genre, the
getGenderString() and getFavoriteGenreString() methods are called to display the field values
in a more human - friendly format.

After the member details come the access log entries. These are displayed in a similar way to the
members in the view_members.php script. For each log entry, the page URL, number of visits, and last
access date are displayed in a table row. Finally, at the end of the page, a JavaScript link is created to
allow the user to go back to the member list page.

Testing the Application

Now that you ’ ve created all the scripts for the application, it ’ s time to try it out. Open the view_
members.php script ’ s URL in your Web browser. You should see a page similar to Figure 13 - 1. Try
moving through the pages (there should be two) using the “Next page” and “Previous page” links, and
changing the sort order by clicking the column headings.
