Example #1 ftp_cdup() example
<?php
// stabilisce la connessione
$conn_id = ftp_connect($ftp_server);
// si collega con nome utente e password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// cambia la directory corrente in html
ftp_chdir($conn_id, 'html');
echo ftp_pwd($conn_id); // /html
// torna alla directory padre
if (ftp_cdup($conn_id)) {
echo "cdup successful\n";
} else {
echo "cdup not successful\n";
}
echo ftp_pwd($conn_id); // /
ftp_close($conn_id);
?>
Restituisce true in caso di successo, false in caso di fallimento.
