$cur_date=date("d-m-Y H-i");

$date = $cur_date;

$data="$conname$cnname\\r\\n";

$fh = fopen("C://$date.txt", "a");

fwrite($fh, $data);

//simpan di FTP

$data1="$conname$cnname\r\n";

$temp = tmpfile();

@ftp_site($conn_ftp,"CHMOD 0777 /");

@ftp_fput($conn_ftp, "$date.txt", $temp, FTP_ASCII);

$fp = fopen("$date.txt", "w");
