How can session management be effectively utilized in PHP to remember the state of collapsed menu items for individual users?

To remember the state of collapsed menu items for individual users in PHP, session management can be effectively utilized. This involves storing the collapsed menu items state in the user's session data and retrieving it when the user visits the page again. 

// Start the session
session_start();

// Check if the user has collapsed any menu items
if(isset($_POST['collapsed_items'])) {
    $_SESSION['collapsed_items'] = $_POST['collapsed_items'];
}

// Retrieve the collapsed menu items state for the user
$collapsed_items = isset($_SESSION['collapsed_items']) ? $_SESSION['collapsed_items'] : [];

// Use $collapsed_items to display the menu items accordingly
