X-Sendfile notification after finish download - php

Question

I would need to set the download status to 0 when download has finished. I am using x-sendfile, but after finish download, dont set status.
My code:
header("X-Sendfile: $file");
header("Content-type: application/octet-stream");
header('Content-Disposition: attachment; filename="' . $name . '"');
mysql_query("UPDATE `downloads` SET `download_status` = '1' WHERE `id` = '" . $last_down . "'");
Thanks for help

You can't detect when the client finished downloading the file if you using X-Sendfile.
Simplest way is stream file by script.
$handle = fopen($filepath, 'rb');
if ($handle !== false) {
#flock($handle, LOCK_SH);
$size = filesize($filepath);
$filename = basename($filepath);
$old_max_execution_time = ini_get('max_execution_time');
ini_set('max_execution_time', 0);
$old_cache_limiter = session_cache_limiter();
session_cache_limiter(false);
if (ob_get_length()) ob_clean();
header('Content-Type: application/octet-stream');
header('Content-Transfer-Encoding: binary');
header('Content-disposition: attachment; filename="'. $filename .'"');
header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
header('Accept-Ranges: bytes');
header('Cache-control: private');
header('Pragma: private');
set_time_limit(0);
while (! feof($handle) && (connection_status() === 0)) {
if (! $buffer = #fread($handle, $interval)) {
// Error
exit;
}
print($buffer);
flush();
}
#flock($handle, LOCK_UN);
#fclose($handle);
ini_set('max_execution_time', $old_max_execution_time);
session_cache_limiter($old_cache_limiter);
// ----------------------------------------------------
// Downloading complete!
// Here you can update your table row in DB...
// ----------------------------------------------------
exit;
}
