How does using sessions in PHP forms compare to using "Richtige Formulare" for better user experience and data integrity?

When using sessions in PHP forms, the user's data is stored on the server side, ensuring better data integrity and security. However, this might lead to a less seamless user experience as the user might need to re-enter their information if the session expires. On the other hand, using "Richtige Formulare" (proper forms) can provide a better user experience by storing the data on the client side, but it might compromise data integrity and security. 

<?php
session_start();

// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Store form data in session variables
    $_SESSION['username'] = $_POST['username'];
    $_SESSION['email'] = $_POST['email'];
    
    // Redirect to another page
    header("Location: next_page.php");
    exit;
}
?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <label for="username">Username:</label>
    <input type="text" id="username" name="username">
    
    <label for="email">Email:</label>
    <input type="email" id="email" name="email">
    
    <button type="submit">Submit</button>
</form>
