How can you implement previous/next buttons in PHP while maintaining user selections?

When implementing previous/next buttons in PHP while maintaining user selections, you can achieve this by storing the user's selections in session variables. This way, when the user navigates between pages using the previous/next buttons, their selections will be preserved. 

<?php
session_start();

// Check if user has made a selection
if(isset($_POST['selection'])){
    $_SESSION['selection'] = $_POST['selection'];
}

// Display previous/next buttons
echo '<a href="page1.php">Previous</a>';
echo '<a href="page3.php">Next</a>';

// Display user's selection
if(isset($_SESSION['selection'])){
    echo 'User selection: ' . $_SESSION['selection'];
}
?>
