* - for methods that expose many signatures, only one can be picked (we
* could in priciple check if signatures differ only by number of params
* and not by type, but it would be more complication than we can spare time)
* - nested xmlrpc params: the caller of the generated php function has to
* encode on its own the params passed to the php function if these are structs
* or arrays whose (sub)members include values of type datetime or base64
*
* Notes: the connection properties of the given client will be copied
* and reused for the connection used during the call to the generated
* php function.
* Calling the generated php function 'might' be slow: a new xmlrpc client
* is created on every invocation and an xmlrpc-connection opened+closed.
* An extra 'debug' param is appended to param list of xmlrpc method, useful
* for debugging purposes.
*
* @param xmlrpc_client $client an xmlrpc client set up correctly to communicate with target server
* @param string $methodname the xmlrpc method to be mapped to a php function
* @param array $extra_options array of options that specify conversion details. valid ptions include
* integer signum the index of the method signature to use in mapping (if method exposes many sigs)
* integer timeout timeout (in secs) to be used when executing function/calling remote method
* string protocol 'http' (default), 'http11' or 'https'
* string new_function_name the name of php function to create. If unsepcified, lib will pick an appropriate name
* string return_source if true return php code w. function definition instead fo function name
* bool encode_php_objs let php objects be sent to server using the 'improved' xmlrpc notation, so server can deserialize them as php objects
* bool decode_php_objs --- WARNING !!! possible security hazard. only use it with trusted servers ---
* mixed return_on_fault a php value to be returned when the xmlrpc call fails/returns a fault response (by default the xmlrpcresp object is returned in this case). If a string is used, '%faultCode%' and '%faultString%' tokens will be substituted with actual error values
