What are some best practices for handling session data when exporting it to a CSV file in PHP?

When exporting session data to a CSV file in PHP, it's important to properly handle the data and ensure it is formatted correctly for CSV. One best practice is to loop through the session data and write each row to the CSV file using fputcsv() function, which automatically handles escaping and formatting the data. Additionally, it's recommended to set the appropriate headers to force the browser to download the file as a CSV. 

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

// Set headers for CSV file download
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="session_data.csv"');

// Open file handle for writing
$fp = fopen('php://output', 'w');

// Loop through session data and write to CSV file
foreach ($_SESSION as $data) {
    fputcsv($fp, $data);
}

// Close file handle
fclose($fp);
