What are the advantages and disadvantages of storing information in session arrays compared to passing them through hidden input fields in PHP forms?

Storing information in session arrays in PHP provides the advantage of keeping the data secure on the server-side and accessible across multiple pages without the need to pass it through hidden input fields in forms. However, this approach may consume more server resources and could potentially lead to scalability issues if too much data is stored in sessions. On the other hand, passing data through hidden input fields in forms is lightweight and does not require server-side storage, but it may expose sensitive information to the client-side. 

// Storing information in session array
session_start();
$_SESSION['username'] = 'JohnDoe';
$_SESSION['email'] = 'johndoe@example.com';

// Accessing the stored information on another page
session_start();
$username = $_SESSION['username'];
$email = $_SESSION['email'];
echo "Username: $username, Email: $email";
