How can the use of while loops in PHP be optimized for better performance and efficiency when working with MySQL data?

When working with MySQL data in PHP using while loops, it is important to optimize the loop for better performance and efficiency. One way to achieve this is by fetching all the data from the database at once and then iterating over the results using a while loop. This reduces the number of queries sent to the database, resulting in improved performance. 

// Fetch all data from MySQL database
$result = mysqli_query($conn, "SELECT * FROM table");
$data = mysqli_fetch_all($result, MYSQLI_ASSOC);

// Iterate over the data using a while loop
foreach($data as $row) {
    // Process each row of data here
}
