Exelente artigo...
esse código pode ajudar e muito na vida de um progamador quando quer mudar de servidor...

Olá Marco,
A variavel $files vem da transformação do array f[] na função:
foreach ($f as $files)

Quanto a sua necessidade, passo um exemplo retirado da php.net que mostra como fazer:

Friends,
If you wanna upload files from your harddisk by a form to a specified ftp this sample can help you...
First of all create the form:
<html>

<body marginwidth=4 marginheight=4 topmargin=4 leftmargin=4 bgcolor=white vlink="#0000ff" link="#0000ff">

<form name="Attachments" method=POST action="sendimage.php" enctype="multipart/form-data">

<input type=hidden name=box value="">

<tr>
<td nowrap width="1%">&nbsp;&nbsp;Image:</td>
<td colspan=2>
<input type=file name=source_file size=20> <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

</td>
</tr>
<input type=submit name=btnSubmit value=Submit size=20 style="border: 1px solid #0000FF"></form>
</body>
</html>

The critical point in this form is the usage of enctype="multipart/form-data"
If you don't use this part your upload operations won't work.
Then u must create sendimage.php as follows:

<?php

$ftp_server='190.148.20.201';//serverip
$conn_id = ftp_connect($ftp_server);


// login with username and password
$user="username";
$passwd="*****";
$login_result = ftp_login($conn_id, $user, $passwd);

// check connection
if ((!$conn_id) || (!$login_result)) {
echo "FTP connection has failed!";
echo "Attempted to connect to $ftp_server for user $ftp_user_name";
die;
} else {
echo "<br>Connected to $ftp_server, for user $user<br>";
}
//directorylike /www.velibaba.com/images
ftp_chdir($conn_id, "www.velibab.com");
ftp_chdir($conn_id, "compimages");

//$destination_file=ftp_pwd($conn_id);

$destination_file="x.jpg";
echo ("<br>");
print $destination_file;

echo ("<br>");

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

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

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

In this example code $source_file is the path of the file in your disk, and destination file is the name of the uploaded file in ftpserver.
In this code I use ftp_chdir to give the path of the
uploaded file within ftpserver..

Marco disse:
Da onde vem o valor da variavel $files?
Nao seria $file?

Codigo:
if ($ftp->srv2srv($LOCAL_SERVER_DIR . $files, $files)) {


Estou perguntando isso porque estou fazendo um script que envia arquivos via FTP, user2server e vi que a funcao para upload

ftp_put($conn_id, "$arqServidor", "$arqLocal", FTP_ASCII);

Precisa do arquivo de origem e o de destino.
Como faco para colocar somente um campo no formulario de envio (o arquivo de origem) ?
Ex:
origem: D:\Imagens\vasco.jpg
destino: vasco.jpg

Eu teria q manipular a string $arqServidor?

Obrigado,


Marco Modesto.

Obrigado Alessander,
Desejei colocar a alteração lá, mas deveria preencher formulários e tal que enviei um e-mail para o Max V. Moiseenko o criador da classe.
Então, coloquei minha contribuição na php.net em http://br2.php.net/manual/en/function.ftp-fput.php
Obtigado!

Alessander Thomaz disse:
Parabéns pelo artigo, nunca pensei na possibilidade de fazer tal operação e pelo que li é muito simples.

Você colocou no phpclasses a modificação que você fez? Seria muito interessante.

Obrigado, Alessander
