What are the potential pitfalls of using while loops in PHP for data output in tables?

One potential pitfall of using while loops in PHP for data output in tables is that it can lead to infinite loops if not properly controlled. To avoid this, it is essential to include a condition within the while loop that will eventually evaluate to false, thus breaking the loop. Additionally, it is important to ensure that the data being fetched and processed within the loop is valid to prevent unexpected behavior. 

// Example of using a while loop with a condition to output data in a table
echo "<table>";
while($row = mysqli_fetch_assoc($result)) {
    echo "<tr>";
    echo "<td>" . $row['column1'] . "</td>";
    echo "<td>" . $row['column2'] . "</td>";
    // Add more columns as needed
    echo "</tr>";
}
echo "</table>";
