What are the potential pitfalls of using hidden fields to pass variables in PHP scripts that refresh every few seconds?

Using hidden fields to pass variables in PHP scripts that refresh every few seconds can lead to security vulnerabilities such as tampering and injection attacks. To mitigate these risks, it is recommended to use sessions or cookies to store and retrieve variables instead of hidden fields. 

<?php
session_start();

// Set the variable in the session
$_SESSION['variable'] = 'value';

// Retrieve the variable from the session
$variable = $_SESSION['variable'];
?>
