How can PHP effectively stream file downloads to users without interruptions?

To effectively stream file downloads to users without interruptions in PHP, you can use the `readfile()` function combined with setting appropriate headers to handle the download process. This allows the file to be streamed directly to the user's browser without loading the entire file into memory, ensuring a smooth and uninterrupted download experience. 

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

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;
