ftp_pasv

(PHP 4, PHP 5)

ftp_pasv — Attivaa o disattiva il modo passivo

Descrizione

bool ftp_pasv ( resource $ftp_stream , bool $pasv )

ftp_pasv() attiva il modo passivo se il parametro pasv e' TRUE. Disattiva il modo passivo se pasv e' FALSE. Nel modo passivo, le connessioni sono iniziate dal client piuttosto che dal server.

Example #1 Esempio di funzione ftp_pasv()

<?php
$file 
'somefile.txt';
$remote_file 'readme.txt';

// stabilisce la connessione
$conn_id ftp_connect($ftp_server);

// si collega con username and password
$login_result ftp_login($conn_id$ftp_user_name$ftp_user_pass);

// attiva il modo passivo
ftp_pasv($conn_idtrue);

// trasferisce un file al server
if (ftp_put($conn_id$remote_file$fileFTP_ASCII)) {
 echo 
"$file trasferito correttamente\n";
} else {
 echo 
"Si e' verificato un problema durante il trasferimento di $file\n";
}

// chiude la connessione
ftp_close($conn_id);
?>

Restituisce TRUE in caso di successo, FALSE in caso di fallimento.

Directly from bsd FTP manual pages:

The PASV command requests that the remote server open a port for the data connection and return the address of that port.  The remote server listens on that port and the client connects to it.

                 When using the more traditional PORT command, the client listens on a port and sends that address to the remote server, who connects back to it.  Passive mode is useful when using ftp through a gateway router or host that controls the directionality of traffic.  (Note that though ftp servers are required to support the PASV command by RFC 1123, some do not.)

PASV: For ftp users behind firewall, the server LISTEN for a connection.

Non-PASV: The client LISTEN for a connection from server.
