What alternative methods can be used to handle empty fields in MySQL queries in PHP?

When handling empty fields in MySQL queries in PHP, one alternative method is to use the COALESCE function in the query to replace empty fields with a default value. This ensures that the query does not return NULL values for empty fields. 

// Example query using COALESCE to handle empty fields
$query = "SELECT COALESCE(column_name, 'default_value') AS column_name FROM table_name";
$result = mysqli_query($connection, $query);

// Fetching and displaying the results
while ($row = mysqli_fetch_assoc($result)) {
    echo $row['column_name'] . "<br>";
}
