What are the best practices for querying and handling empty fields in a MySQL table using PHP?

When querying a MySQL table in PHP, it's important to handle empty fields properly to avoid errors or unexpected behavior. One common approach is to check if the field is empty before using its value in your code, and handle it accordingly. This can be done using functions like `isset()` or `empty()` in PHP. 

// Query the MySQL table
$query = "SELECT * FROM table_name";
$result = mysqli_query($connection, $query);

// Fetch data and handle empty fields
while ($row = mysqli_fetch_assoc($result)) {
    $field1 = isset($row['field1']) ? $row['field1'] : 'N/A';
    $field2 = !empty($row['field2']) ? $row['field2'] : 'N/A';

    // Use the values of $field1 and $field2 in your code
}
