How can session IDs be effectively used to track user actions and prevent multiple ratings in a PHP application?

To track user actions and prevent multiple ratings in a PHP application using session IDs, you can store the user's session ID along with their rating in a database table. Before allowing a user to submit a rating, check if their session ID has already rated the item. If it has, prevent the user from submitting another rating. 

// Start the session
session_start();

// Check if the user has already rated the item
if(isset($_SESSION['session_id'])) {
    $session_id = $_SESSION['session_id'];
    
    // Check if the session ID has already rated the item
    $query = "SELECT * FROM ratings WHERE session_id = :session_id AND item_id = :item_id";
    // Execute the query and check if a row is returned
    // If a row is returned, prevent the user from submitting another rating
}

// If the user hasn't rated the item, allow them to submit a rating
