How can the use of header redirection affect the persistence of PHP class instances and data?

When using header redirection in PHP, the script sends a new HTTP header to the browser, which can cause issues with the persistence of PHP class instances and data. To solve this issue, you can use output buffering to store the output before sending any headers, allowing you to manipulate data and class instances before redirection. 

<?php
ob_start();

// Your PHP code here

// Store class instances and data in variables

ob_end_clean();
header("Location: new_page.php");
exit;
?>
