R: [phpxmlrpc] Problems with example (first webservice)

Wed Nov 24 05:41:30 PST 2004

I pasted your code on my webserver (brr.....) and it worked OK.

Hints:

1 - what the xmlrpc caller is getting IS NOT valid XML (the mesage tells you that)

2 - it's probably due to an error in the xmlrpc server page. If you have error_diplay = ON in PHP.INI, the php error will be printed to the web server page, which in this case is the XML that the client expects to receive.

3 - use $client->setDebug(true); to have the client dump to screen (to the web browser) the garbage it is receiving from the server.

4 - since the code you're writing is quite short, I suspect the directory where you dumped xmlrpc.inc and xmlrpcs.inc is not in your include path...

bye
