+ * in the @param tag is also allowed, if you need the php function to receive/send
+ * data in that particular format (note that base64 enncoding/decoding is transparently
+ * carried out by the lib, while datetime vals are passed around as strings)
+ *
+ * Known limitations:
+ * - requires PHP 5.0.3 +
+ * - only works for user-defined functions, not for PHP internal functions
+ * (reflection does not support retrieving number/type of params for those)
+ * - functions returning php objects will generate special xmlrpc responses:
+ * when the xmlrpc decoding of those responses is carried out by this same lib, using
+ * the appropriate param in php_xmlrpc_decode, the php objects will be rebuilt.
+ * In short: php objects can be serialized, too (except for their resource members),
+ * using this function.
+ * Other libs might choke on the very same xml that will be generated in this case
+ * (i.e. it has a nonstandard attribute on struct element tags)
+ * - usage of javadoc @param tags using param names in a different order from the
+ * function prototype is not considered valid (to be fixed?)
+ *
+ * Note that since rel. 2.0RC3 the preferred method to have the server call 'standard'
+ * php functions (ie. functions not expecting a single xmlrpcmsg obj as parameter)
+ * is by making use of the functions_parameters_type class member.
+ *
+ * @param string $funcname the name of the PHP user function to be exposed as xmlrpc method; array($obj, 'methodname') might be ok too, in the future...
+ * @return false on error, or an array containing the name of the new php function,
