How can you ensure that new news articles are displayed at the top of the list in a PHP news system?

To ensure that new news articles are displayed at the top of the list in a PHP news system, you can add a timestamp field to the news articles database table and sort the articles by this timestamp in descending order when fetching them for display. This way, the latest news articles will always appear at the top of the list.

// Assuming you have a database table named 'news_articles' with columns 'id', 'title', 'content', and 'timestamp'

// Fetch news articles sorted by timestamp in descending order
$query = "SELECT * FROM news_articles ORDER BY timestamp DESC";
$result = mysqli_query($connection, $query);

// Display news articles
while ($row = mysqli_fetch_assoc($result)) {
    echo "<h2>{$row['title']}</h2>";
    echo "<p>{$row['content']}</p>";
    echo "<p>Published on: " . date('F j, Y, g:i a', strtotime($row['timestamp'])) . "</p>";
}
