Ssh error and ftp error and PHP extension problems

[SUYUKJ]

The ssh function cannot upload files, the ftp function cannot be connected, the server side shows that the ftp link is successful, but the app shows that it is in the link. Later, it will appear: NSURLERRORDOMAIN-1017 error. How to turn on a specific extension in PHP local operation? He can't even use the curl extension???
