What are the potential security risks of not using sessions to store sensitive data in PHP applications?

Storing sensitive data in PHP applications without using sessions can expose the information to potential security risks such as unauthorized access, data leakage, and interception. To mitigate these risks, it is recommended to store sensitive data in session variables which are more secure and can only be accessed by the user during their session. 

<?php
session_start();

// Store sensitive data in session variable
$_SESSION['sensitive_data'] = 'my_secret_info';

// Access the sensitive data
echo $_SESSION['sensitive_data'];
?>
