Re: Hoping for a working example of SFTP in PHP

Just a few questions.  What web server do you use?  And how did you install
it on windows.  I'll do the same install.  It seems to me that it is
something to do with the web server.

It could even be that the stream is disabled on apache or fpm to prevent
people from trying to connect to root@localhost, or administrator@localhost.
You said ssh2_scp_send does work?
