Been banging my head on this all day, so here's the stoopid question:
Do we *really need* the xml-rpc extension to create a xmlrpc
webservice ?
I'm getting the impression that we're supposed to generate the XML by hand.
That's why PHP 5.1.2 has DOM methods as well as an xmlwriter class.
And invoking the webserver "function/class" can be done by general PHP code
as well, no need for *registering the method with the server* ?
Many webauthors urge us to precede any xml output with : header('Content-
Type: text/xml');
So if we have to do all that ourselves, what work does the xml-rpc
extension actually do ?
Below is my first webservice effort, using POST.
The js-client sends "Kilroy", and the webservice appends ' was here'.
I'm receiving an XML object all right, but it appears empty.
Any help appreciated...
