I want to try out some of the example queries but I dont know how to send out the request using PHP and the tutorials I found haven't helped very much. Is there a certain function that I need to use? If so, how do I call it? Should I be using a certain SOAP toolkit? I want to build the site in Joomla with the VirtueCart plug-in.

I tried registering on the Web Services forum where I can ask some of the same questions but their registration form doesnt work and all the forums seem to be marked "Quiet" - I see no "Active" forums.

Can anyone put me on the right track?
