What is the purpose of the code provided and what issue is the user experiencing with empty rows in the database?

The issue the user is experiencing with empty rows in the database is likely due to the fact that the code is not properly handling or filtering out empty rows when retrieving data from the database. To solve this issue, the user should modify the SQL query to exclude empty rows or filter them out before processing the data. 

// Connect to the database
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Query to retrieve data from the database excluding empty rows
$sql = "SELECT * FROM your_table WHERE column_name != ''";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "id: " . $row["id"]. " - Name: " . $row["name"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
