Do you want your Perl code on one server to call your PHP functions on another? "Impossible!" you say? Not with XML-RPC. XML-RPC is a standard way for any application to make requests and recieve responses from methods written in any language. Interested? I knew you would be.

<string>Hello Lucas. How are you today?</string>
With your newly found knowledge of XML-RPC calls, it is easy
to decipher standard responses. Normal responses consist of <params> container with <param> elements (and all they are heir to) sent inside <methodResponse> tags, but there is another type of response - a fault:
As you can see, a fault response consists of a
<methodResponse> containing a <fault> which contains a <value> which is a <struct> containing two elements, one named <faultCode>, an <int> and one named <faultString>, a <string>.
Please note that a response cannot contain both a <params> container and a <fault> container.
