How can the "while" loop be utilized in PHP to efficiently iterate through database query results and display them correctly?

When iterating through database query results in PHP, using a "while" loop is an efficient way to fetch and display each row of data until there are no more results left. This loop structure allows you to process each row individually and display it as needed. To use a "while" loop with database query results, you need to fetch rows from the query result set and then loop through them using the "while" loop until there are no more rows left to process. 

// Assume $result is the database query result
while ($row = mysqli_fetch_assoc($result)) {
    // Process and display each row of data
    echo $row['column1'] . ' - ' . $row['column2'] . '<br>';
}
