How can PHP developers prevent users from manipulating page view counts through cookies or session data?

To prevent users from manipulating page view counts through cookies or session data, PHP developers can implement server-side tracking mechanisms that store view counts in a secure database. By using server-side tracking, developers can ensure that view counts are accurate and cannot be easily manipulated by users. 

// Example PHP code snippet to prevent users from manipulating page view counts

// Connect to database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "view_counts";

$conn = new mysqli($servername, $username, $password, $dbname);

// Increment page view count
$page_id = 1; // Example page ID
$sql = "UPDATE page_views SET count = count + 1 WHERE page_id = $page_id";
$conn->query($sql);

// Retrieve and display page view count
$sql = "SELECT count FROM page_views WHERE page_id = $page_id";
$result = $conn->query($sql);
$row = $result->fetch_assoc();
echo "Page views: " . $row['count'];

// Close database connection
$conn->close();
