How can session variables be utilized in PHP to store form data for confirmation dialogs?

Session variables can be utilized in PHP to store form data for confirmation dialogs by storing the form data in session variables when the form is submitted and then retrieving and displaying the data on the confirmation page. This allows the user to review the information they entered before finalizing the submission. 

<?php
session_start();

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $_SESSION['name'] = $_POST['name'];
    $_SESSION['email'] = $_POST['email'];
    // Store other form data in session variables as needed
    header("Location: confirmation.php");
    exit();
}
?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <input type="text" name="name" placeholder="Name">
    <input type="email" name="email" placeholder="Email">
    <!-- Add other form fields here -->
    <button type="submit">Submit</button>
</form>
