How can the user modify the code to properly handle the mysqli connection and query without using the Datenbank class?

The user can modify the code to properly handle the mysqli connection and query by directly using the mysqli functions instead of relying on the Datenbank class. This involves establishing a connection to the database using mysqli_connect(), executing the query with mysqli_query(), and fetching the results using mysqli_fetch_assoc(). 

// Establish connection to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = mysqli_connect($servername, $username, $password, $dbname);

// Check connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

// Execute query
$sql = "SELECT * FROM table_name";
$result = mysqli_query($conn, $sql);

// Fetch results
if (mysqli_num_rows($result) > 0) {
    while($row = mysqli_fetch_assoc($result)) {
        echo "Column1: " . $row["column1"]. " - Column2: " . $row["column2"]. "<br>";
    }
} else {
    echo "0 results";
}

// Close connection
mysqli_close($conn);
