How can the SQL statement be modified to order the data by the field "spieler" in descending order?

To order the data by the field "spieler" in descending order, you can modify the SQL statement by adding "ORDER BY spieler DESC" at the end of the query. This will sort the results in descending order based on the "spieler" field.

$sql = "SELECT * FROM tablename ORDER BY spieler DESC";
$result = mysqli_query($connection, $sql);

if (mysqli_num_rows($result) > 0) {
    while($row = mysqli_fetch_assoc($result)) {
        // Output data
    }
} else {
    echo "0 results";
}
