    // connect to ftp server
    $ftpConnID = ftp_connect($ftpServer);

    if (@ftp_login($ftpConnID, $ftpUsername, $ftpPassword)){
        // successfully connected
    }else{
        // Error to log-in in ftp
        return false;
    }
    if(ftp_put(ftp_put($ftpConnID, $remoteFile, $localFile, FTP_ASCII) {
      echo "File uploaded successfully";
     } else {
      echo "Error to upload file on FTP server";
     }
    // close connection
    ftp_close($connection);
}
