How can PHP developers troubleshoot and resolve download interruptions for users with different operating systems and browsers?

Users experiencing download interruptions on different operating systems and browsers may be due to inconsistent handling of file downloads. PHP developers can troubleshoot and resolve this issue by setting appropriate headers to ensure a smooth download process for all users. 

<?php
$file = 'example.pdf';
if (file_exists($file)) {
    header('Content-Description: File Transfer');
    header('Content-Type: application/pdf');
    header('Content-Disposition: attachment; filename="'.basename($file).'"');
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' . filesize($file));
    readfile($file);
    exit;
} else {
    echo 'File not found.';
}
?>
