Example #1 cubrid_column_names() example

    <?php
    $conn = cubrid_connect("localhost", 33000, "demodb", "dba");
    $result = cubrid_execute($conn, "SELECT * FROM game WHERE host_year=2004 AND nation_code='AUS' AND medal='G'");

    $column_names = cubrid_column_names($result);
    $column_types = cubrid_column_types($result);

    printf("%-30s %-30s %-15s\n", "Column Names", "Column Types", "Column Maxlen");
    for($i = 0, $size = count($column_names); $i < $size; $i++) {
        $column_len = cubrid_field_len($result, $i);
        printf("%-30s %-30s %-15s\n", $column_names[$i], $column_types[$i], $column_len);
    }

    cubrid_disconnect($conn);
    ?>

以上例程会输出：

    host_year                      integer                        11
    event_code                     integer                        11
