How can the Internet Explorer's behavior towards Content-Disposition headers be managed when serving PDF files with PHP?

Internet Explorer may not always handle Content-Disposition headers correctly when serving PDF files with PHP, leading to issues with file downloads. To manage this behavior, you can set the Content-Type header to "application/pdf" and include the Content-Disposition header with the "attachment" parameter in your PHP code. This will prompt the browser to download the PDF file instead of trying to open it in the browser window. 

<?php
$file = 'example.pdf';
header('Content-Type: application/pdf');
header('Content-Disposition: attachment; filename="' . basename($file) . '"');
readfile($file);
exit;
?>
