Thank you, good point! As ftp_raw() is PHP5 only and the application is
supposed to run from PHP 4.3 upwards, I added reduction of the timeout
period, so the number of possibly open connections on the server should
be reduced to a reasonable amount:

if (function_exists('ftp_raw')) {
ftp_raw($ftpconn, 'QUIT');
}
else {
ftp_set_option($ftpconn, FTP_TIMEOUT_SEC, 1);
}
ftp_close($ftpconn);
