What is the purpose of the loop in the code and how does it affect the retrieval of data?

The purpose of the loop in the code is to iterate through each row of data retrieved from the database query results. This loop allows us to process each row individually and extract the data we need. Without the loop, we would only retrieve the first row of data. 

// Assuming $result contains the database query results
while ($row = mysqli_fetch_assoc($result)) {
    // Process each row of data here
    // Example: echo $row['column_name'];
}
