open a socket on a https server

[ged]

HI

I'd like to make a https request to another web server from my web server,
by opening a socket in PHP.

I know how to do this for HTTP protocol
(I open a socket on the remote server, and I write "GET / HTTP1.0" into the
open socket),

but I don't know for HTTPS.

Can somebody help me ?

Thanks a lot.
