array. When a user adds "Product 1," the system checks if that ID already exists in the session; if it does, it increments the quantity; otherwise, it creates a new entry. Inventory Tracking

// Validate that ID is actually a number if (!is_numeric($id)) die("Invalid ID."); If you share with third parties, their policies apply
