## Adding another view - Department Course Listings

Create another PHP file that displays course information based upon a department_code parameter.

- `courses.php` - take a "department_code" parameter and produce alist of courses for that department.

Need to link to to courses.php:

- courses.php?department_code=CHEM
- courses.php?department_code=DGMD

Modify the department listing to include the hyperlink:

    // Printing results in HTML
    echo "<ul>\n";
    while ($row = $result->fetch_assoc()) {
      echo "<li>";
      echo "<a href=\"courses.php?department_code=$row[department_code]\">"
      echo "$row[department]"
      echo "</a>";
      echo "</li>\n";
    }
    echo "</ul>\n";
