What best practices should be followed when sorting and displaying posts in a PHP-based ticket system?

When sorting and displaying posts in a PHP-based ticket system, it is important to prioritize posts based on their timestamp to ensure that the most recent posts are displayed first. This can be achieved by sorting the posts array in descending order based on the timestamp field.

// Assume $posts is an array of posts with each post having a 'timestamp' field

// Sort posts array in descending order based on timestamp
usort($posts, function($a, $b) {
    return strtotime($b['timestamp']) - strtotime($a['timestamp']);
});

// Display sorted posts
foreach ($posts as $post) {
    echo $post['content'] . '<br>';
}
