ssl — FTPS PHP активный PROT P

Я пытаюсь сделать загрузку файла на FTP-пространстве с ssl подразумевается.

Я подключаю его, чтобы загрузить файл, который он предложил PROT P.

Я огляделся по сторонам, но ничего не нашел, как его активировать.
Вы знаете, помогите мне?

Я оставляю вам мой код и его подробный

$file = "prova_4u.csv";

$ftp_server="mio ftps";
$ftp_user_name="mio user";
$ftp_user_pass="mia pass";
$path="/";
//$file =dirname(__FILE__)."/../application/archivosastras/".$localfile.".csv";
$remote_file = $path.$file;
$ch = curl_init();
$fp = fopen($file,'r');

curl_setopt($ch, CURLOPT_URL, $ftp_server.$remote_file);
curl_setopt($ch, CURLOPT_UPLOAD, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_PORT, 990);

//SSL stuff curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);

//curl_setopt($ch, CURLOPT_USE_SSL, TRUE);
curl_setopt($ch, CURLOPT_FTP_SSL, CURLOPT_FTPSSLAUTH);
curl_setopt($ch, CURLOPT_FTPSSLAUTH, CURLFTPAUTH_TLS);
curl_setopt($ch, CURLOPT_PROTOCOLS, CURLPROTO_FTPS);
curl_setopt($ch, CURLOPT_USERPWD,"$ftp_user_name:$ftp_user_pass");
//curl_setopt($ch,CURLOPT_SSLVERSION, 3);

//end SSL curl_setopt($ch, CURLOPT_INFILESIZE, filesize($file));
$exec = curl_exec ($ch);

echo "\n\r".$exec."\n\r";

$error_no = curl_errno($ch); $error_msg = curl_error($ch);

echo "no - ".$error_no." - ".$error_msg."\n\r\n\r";

curl_close ($ch);

if ($error_no == 0) {   $error = 'File uploaded succesfully.'; } else {
$error = 'File upload error.'; }

echo "\n\r".$error."\n\r";

fclose($fp);
