La funzione ftp_connect() apre una connessione FTP all' host specificato. host non deve essere seguito da barre e non deve essere precedeuto da ftp://. Il parametro port specifica una porta alternativa cui connettersi. Se e' omesso o impostato a zero verra' usata la porta 21, default di FTP.

Il parametro timeout specifica il timeout per tutte le successive operazioni di rete. Se omesso il valore predefinito e' di 90 secondi. Il timeout puo' essere modificato o interrogato in qualsiasi momento con ftp_set_option() e ftp_get_option().

$ftp_server 
"ftp.example.com";

// stabilisce una connessione o esce
$conn_id ftp_connect($ftp_server) or die("Impossibile collegarsi a $ftp_server");

In testing, I have been unable to establish any socket connections (including FTP connections) on shutdown.  This is important if you are trying to save the FTP transfer to run after the php script has been executed (using register_shutdown_function).  I am unaware of any configuration options that control this, and I have found this affects any socket connections I have tried to establish after shutdown.

The same code works fine if it is executed at runtime, rather than on shutdown.  Since I found no documentation of this behavior, I felt it important to note somewhere.  May also be useful if this was crosslinked to fsockopen comments as well.

Connecting through a firewall also depends on the type. This is an example for the Secure Gateway FTP. First you have to connect to the firewall, then open a session to the destination ftp server. This looks like this:

// Connect to firewall
$conn_id = ftp_connect("firewall.yournet.com");

// Open a session to an external ftp site
$login_result = ftp_login ($conn_id, "userid@externalhost.com", "password");

// Check open
if ((!$conn_id) || (!$login_result)) {
        echo "Ftp-connect failed!"; die;
    } else {
        echo "Connected.";
    }

// turn on passive mode transfers
ftp_pasv ($conn_id, true) ;

... and go on ...

always keep an eye on the ftp_pasv function, if you are behind a firewall or nat'ed and your scripts won't do a listing or put files to the ftp
