What are the best practices for sending variables without users being aware of it in PHP?

To send variables without users being aware of it in PHP, it is recommended to use sessions. By storing variables in session data, they are kept on the server-side and not visible to the user. This helps maintain data privacy and security. 

<?php
session_start();

// Set a variable in the session
$_SESSION['secret_variable'] = 'hidden_value';

// Retrieve the variable from the session
$hidden_value = $_SESSION['secret_variable'];

// Use the variable as needed
echo $hidden_value;
?>
