How can headers be manipulated in PHP to control the display of file paths?

To control the display of file paths in PHP, you can use the `header()` function to set the `Content-Disposition` header to specify how the browser should handle the file download. By setting the `Content-Disposition` header to `attachment; filename="desired_filename.extension"`, you can control the display of file paths and force the browser to download the file with the specified filename.

<?php
$file_path = 'path/to/your/file.pdf';
$desired_filename = 'new_filename.pdf';

header('Content-Description: File Transfer');
header('Content-Type: application/pdf');
header('Content-Disposition: attachment; filename="' . $desired_filename . '"');
header('Content-Length: ' . filesize($file_path));

readfile($file_path);
exit;
?>
