Upload a tar file to a ftp server

This is a typical upload routine:

// set up basic connection
$conn_id = ftp_connect($ftp_server);


// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

// check connection
if ((!$conn_id) || (!$login_result)) {
        echo "FTP connection has failed!";
        echo "Attempted to connect to $ftp_server for user $ftp_user_name";
        exit;
    } else {
          echo '<br><br>';
        echo "Connected to $ftp_server, for user $ftp_user_name";
    }
     
$ftp_dir = ftp_pwd($conn_id);
$destination_file = $ftp_dir.$sourcefile_name;
echo "<br>$destination_file";

// upload the file
$upload = ftp_put($conn_id, $destination_file, $sourcefile, FTP_BINARY);

// check upload status
if (!$upload) {
        echo "<br><br>FTP upload has failed!";
    } else {
        echo "<br><br>Uploaded $sourcefile_fix to $ftp_server as $destination_file";
    }

// close the FTP stream
ftp_close($conn_id);

You will need to have downloaded your file previously with filename described by $sourcefile

Yes I seen this example on php.net, but I am not able to make it upload.
Please give me more detailed help with an example.
