Are there specific PHP functions or techniques that can help streamline the process of generating and offering files for download while still providing user feedback?

When generating and offering files for download in PHP, it's important to provide user feedback to ensure a smooth experience. One way to streamline this process is by using the `readfile()` function to efficiently output the file contents to the browser while also providing feedback messages to the user. 

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

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