What are best practices for maintaining form data consistency when navigating between different forms in PHP?

When navigating between different forms in PHP, it is important to maintain form data consistency to ensure a seamless user experience. One way to achieve this is by using sessions to store form data temporarily and populate the form fields with the stored data when navigating between forms. 

// Start or resume a session
session_start();

// Check if form data is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Store form data in session variables
    $_SESSION['form_data'] = $_POST;
    // Redirect to the next form
    header("Location: next_form.php");
    exit();
}

// Retrieve form data from session variables
if (isset($_SESSION['form_data'])) {
    $form_data = $_SESSION['form_data'];
    // Populate form fields with the stored data
    foreach ($form_data as $key => $value) {
        echo '<input type="text" name="' . $key . '" value="' . $value . '">';
    }
}
