XMLRPC for PHP and HTTPS

Hello,

My program work fine with HTTP.

I would like to know what do i have to do to use HTTPS now.

I know i have to compile php with curl and after ?

What change in my config files ? in my script ?
I didn't find documentation :o(

Thanks for your help,
Eric.

Here is a part of my script :
            $server_path="/RPC2";
            $server_hostname="server.insa-toulouse.fr";
            $server_port=8000;


            $client=new xmlrpc_client($server_path, $server_hostname, 
$server_port);
