How can PHP developers ensure that sensitive data is not exposed in URLs when passing variables between pages?

To ensure sensitive data is not exposed in URLs when passing variables between pages, PHP developers can use sessions to store and retrieve the sensitive data instead of passing it through the URL. This helps to keep the data secure and hidden from prying eyes. 

<?php
// Start the session
session_start();

// Set sensitive data in session variable
$_SESSION['sensitive_data'] = 'my_sensitive_data';

// Redirect to another page
header('Location: another_page.php');
exit;
?>
