Are cookies the most effective method for tracking user interactions like pressing a Like button?

Cookies are not the most effective method for tracking user interactions like pressing a Like button because they can easily be manipulated or deleted by the user. A more reliable method would be to use server-side tracking where the interaction is recorded in a database.

// Assuming a user has pressed the Like button, you can track this interaction using server-side tracking

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

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

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Insert user interaction into database
$user_id = $_SESSION['user_id']; // Assuming you have a user session
$interaction_type = "Like";
$item_id = $_POST['item_id']; // Assuming you have an item ID

$sql = "INSERT INTO user_interactions (user_id, interaction_type, item_id) VALUES ('$user_id', '$interaction_type', '$item_id')";

if ($conn->query($sql) === TRUE) {
    echo "User interaction recorded successfully";
} else {
    echo "Error recording user interaction: " . $conn->error;
}

$conn->close();
