ftps (FTPS是一種以擴展常用的文件傳輸協議（FTP）的添加了對傳輸層安全性（TLS）和安全套接字層（SSL）的加密協議的支持。)本身無法使用CI內建的lib去作，需要額外自己建一個libraries。
首先先在libraires中建立一個檔案

我把「file_name」跟「file」(內容)放在建構子中，也就是說一但呼叫了這個class，他就會立即執行上傳的動作；呼叫方式如下：

1 2 3 4 |
$ary_params['file_name'] = $file_name; $ary_params['file'] = file_get_contents($filename); $this->load->library('ftpsUpload', $ary_params ); |
ftps是透過curl的方式上傳，比較特別一點，需要注意一下。
