What are the best practices for implementing a dynamic page history feature in PHP, considering both performance and user experience factors?

Implementing a dynamic page history feature in PHP involves storing the history of visited pages for each user and displaying it in a user-friendly manner. To achieve this, you can use sessions to store the page history and display it using a list or dropdown menu on the webpage. However, to ensure optimal performance, it's important to limit the number of pages stored in the history and properly handle session management. 

// Start the session
session_start();

// Check if the page history array exists in the session
if (!isset($_SESSION['page_history'])) {
    $_SESSION['page_history'] = array();
}

// Add the current page to the page history
array_push($_SESSION['page_history'], $_SERVER['REQUEST_URI']);

// Limit the page history to a certain number of pages
if (count($_SESSION['page_history']) > 10) {
    array_shift($_SESSION['page_history']);
}

// Display the page history in a list
echo '<ul>';
foreach ($_SESSION['page_history'] as $page) {
    echo '<li><a href="' . $page . '">' . $page . '</a></li>';
}
echo '</ul>';
