How can PHP be used to display the newest news articles at the top of a webpage?

To display the newest news articles at the top of a webpage using PHP, you can first retrieve the articles from a database or an external source, sort them by their publication date in descending order, and then loop through the sorted articles to display them on the webpage.

<?php
// Assuming $articles is an array of news articles with keys like 'title' and 'publication_date'
usort($articles, function($a, $b) {
    return strtotime($b['publication_date']) - strtotime($a['publication_date']);
});

foreach ($articles as $article) {
    echo "<h2>{$article['title']}</h2>";
    echo "<p>{$article['publication_date']}</p>";
    // Display other article content here
}
?>
