ftp_ssl_connect z niejawnym ftp ponad tls

Question

Czy ftp_ssl_connect może obsługiwać niejawny FTP przez TLS? Domyślnie używa jawnie.

Próbuję przesłać na serwer, który akceptuje tylko niejawny ftp przez tls na porcie 990; czy ktoś na to nie wpadł? Jak to naprawiłeś?

Answer 1

ftp_ssl_connect jest tylko jawne

jeśli trzeba niejawna użyć curl

$fp = fopen($path, 'r'); 
$ftp_server = 'ftps://'.$server.'/'.$filename; 
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $ftp_server); 
curl_setopt($ch, CURLOPT_USERPWD,$user.':'.$pass); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); 
curl_setopt($ch, CURLOPT_FTP_SSL, CURLFTPSSL_TRY); 
curl_setopt($ch, CURLOPT_FTPSSLAUTH, CURLFTPAUTH_TLS); 
curl_setopt($ch, CURLOPT_UPLOAD, 1); 
curl_setopt($ch, CURLOPT_INFILE, $fp); 

$output = curl_exec($ch); 
$error_no = curl_errno($ch); 
//var_dump(curl_error($ch)); 
curl_close($ch);

Dla każdego, kto się do google po tej stronie i chce szybkiego rozwiązania:

I rozszerzoną na odpowiedź frustrum za i stworzyłem prostą klasę do podstawowego przesyłania/pobierania przy użyciu tej metody. Mam nadzieję, że to pomoże!

Answer 3

Na podstawie odpowiedzi od Stevena Jeffriesa i frustrum rozszerzyłem go dalej. To ponownie wykorzystuje połączenie curl i ma pewne funkcje listowania katalogów, w tym jeden do sortowania plików według ostatniej modyfikacji.

To jest dla PHP 7, dla niższego trzeba będzie przepisać linię operatora < =>.
