How can PHP developers effectively handle page navigation and form submissions without compromising user experience?

To effectively handle page navigation and form submissions in PHP without compromising user experience, developers can utilize sessions to store form data and redirect users back to the previous page after form submission. This ensures that users do not lose their input and can easily navigate back to where they were on the site. 

<?php
session_start();

// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Store form data in session
    $_SESSION['form_data'] = $_POST;
    
    // Redirect back to previous page
    header("Location: " . $_SERVER['HTTP_REFERER']);
    exit;
}

// Retrieve form data from session
if (isset($_SESSION['form_data'])) {
    $form_data = $_SESSION['form_data'];
    // Use form data as needed
    unset($_SESSION['form_data']); // Clear form data from session
}
?>
