What are the advantages and disadvantages of using a session to store directory information in PHP?

Storing directory information in a session in PHP can be useful for maintaining user-specific data across multiple pages. However, it can also lead to potential security risks if sensitive information is stored in the session. It is important to properly sanitize and validate the data before storing it in the session to mitigate these risks. 

<?php
session_start();

// Store directory information in session
$_SESSION['directory'] = '/path/to/directory';

// Retrieve directory information from session
$directory = $_SESSION['directory'];

// Ensure data is properly sanitized and validated before storing in session
// For example:
$clean_directory = filter_var($directory, FILTER_SANITIZE_STRING);
?>
