                    <?php
                    $cars = array (

                    for ($row = 0; $row < 4; $row++) {
                      echo "<p><b>Row number $row</b></p>";
                      echo "<ul>";
                      for ($col = 0; $col < 3; $col++) {
                        echo "<li>".$cars[$row][$col]."</li>";
                      }
