What are the best practices for handling simultaneous delivery of binary data (downloads) and webpage redirection in PHP?

When handling simultaneous delivery of binary data (downloads) and webpage redirection in PHP, it is essential to use output buffering to prevent headers from being sent prematurely. You can achieve this by buffering the output, sending the headers for the binary data download, and then redirecting the user to another page. 

<?php
ob_start();

// Send headers for binary data download
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="file.zip"');
readfile('path/to/file.zip');

// Clean the output buffer
ob_end_clean();

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