Are there any best practices for handling file downloads in PHP to avoid unexpected behavior like the one described in the forum thread?

Issue: The unexpected behavior described in the forum thread could be due to improper handling of file downloads in PHP. To avoid such issues, it is recommended to set appropriate headers before outputting the file content to ensure a smooth download process. Solution: 

$file = 'path/to/file.pdf';

if (file_exists($file)) {
    header('Content-Description: File Transfer');
    header('Content-Type: application/pdf');
    header('Content-Disposition: attachment; filename=' . basename($file));
    header('Content-Length: ' . filesize($file));
    readfile($file);
    exit;
} else {
    echo 'File not found.';
}
