What are the potential pitfalls of using while loops within while loops in PHP for data retrieval and display?

Using while loops within while loops for data retrieval and display can lead to issues such as infinite looping, performance degradation, and complexity in code maintenance. To avoid these pitfalls, it's recommended to use a single loop to retrieve and display data in a more efficient and manageable way.

// Example of using a single while loop for data retrieval and display

// Assume $result is the result set from a database query
while ($row = mysqli_fetch_assoc($result)) {
    // Display data from the current row
    echo $row['column_name'] . "<br>";
}
