What are best practices for handling result sets in PHP?

When handling result sets in PHP, it is best practice to loop through the result set using a while loop to fetch each row one by one. This allows you to process each row individually and avoid memory issues that may arise from loading the entire result set into memory at once. 

// Assuming $result is the result set from a database query

while ($row = mysqli_fetch_assoc($result)) {
    // Process each row here
    echo $row['column_name'] . "<br>";
}
