How can arrays be effectively utilized to store and retrieve multiple values from form submissions in PHP sessions, as demonstrated in the forum thread?

To store and retrieve multiple values from form submissions in PHP sessions, arrays can be effectively utilized. By storing form data in an array within the session variable, you can easily access and manipulate the submitted values throughout the user's session. This approach allows for efficient organization and retrieval of multiple form inputs without cluttering the session with individual variables. 

// Start the session
session_start();

// Check if form data is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Initialize an array to store form data
    $formData = [];

    // Store form inputs in the array
    $formData['name'] = $_POST['name'];
    $formData['email'] = $_POST['email'];
    $formData['message'] = $_POST['message'];

    // Store the array in the session variable
    $_SESSION['formData'] = $formData;
}

// Retrieve form data from the session
if (isset($_SESSION['formData'])) {
    $formData = $_SESSION['formData'];

    // Access individual form inputs
    $name = $formData['name'];
    $email = $formData['email'];
    $message = $formData['message'];

    // Display or use the form data as needed
    echo "Name: $name<br>";
    echo "Email: $email<br>";
    echo "Message: $message<br>";
}
