How can PHP developers avoid common pitfalls when working with multiple query results and displaying them in a user-friendly manner?

When working with multiple query results in PHP, developers should avoid directly outputting raw data to the user interface. Instead, they should iterate through the results and format them in a user-friendly manner before displaying them. This can be achieved by using HTML and CSS to structure and style the data appropriately for better readability.

<?php
// Assume $results is an array of query results

echo '<div class="results-container">';
foreach ($results as $result) {
    echo '<div class="result">';
    echo '<h2>' . $result['title'] . '</h2>';
    echo '<p>' . $result['description'] . '</p>';
    echo '</div>';
}
echo '</div>';
?>
