What are the potential pitfalls or challenges when trying to customize the visual presentation of MySQL query results in PHP, and how can they be addressed?

One potential challenge when customizing the visual presentation of MySQL query results in PHP is ensuring that the data is displayed in a visually appealing and user-friendly format. This can be addressed by using HTML and CSS to style the output of the query results.

<?php
// Perform MySQL query
$query = "SELECT * FROM table_name";
$result = mysqli_query($connection, $query);

// Display query results in a table format
echo "<table>";
while ($row = mysqli_fetch_assoc($result)) {
    echo "<tr>";
    foreach ($row as $key => $value) {
        echo "<td>$value</td>";
    }
    echo "</tr>";
}
echo "</table>";
?>
