ftp_ssl_connect隱含ftp over tls

Question

ftp_ssl_connect可以通過TLS處理隱式FTP嗎？默認情況下它使用顯式。

我想上傳到一個服務器，只接受端口990 tls上的隱式ftp;有沒有人遇到過這個問題呢？你怎麼修好它的？

Answer 1

ftp_ssl_connect是唯一明確

如果你需要含蓄，用捲曲

$fp = fopen($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);

對於任何人誰發生在此頁面，谷歌，並希望一個快速的解決方案：

我對截的答案擴大並使用此方法爲基本上傳/下載做了一個簡單的類。我希望它有幫助！

基於frustrum和Steven Jeffries的回答，我進一步擴展了它。這重用了curl連接並具有一些目錄列表功能，其中包括通過上次修改對文件進行排序的功能。

這是PHP 7，對於較低的你將不得不重寫< =>操作員行。
