-	/**
-	* Given a user-defined PHP function, create a PHP 'wrapper' function that can
-	* be exposed as xmlrpc method from an xmlrpc_server object and called from remote
-	* clients (as well as its corresponding signature info).
-	*
-	* Since php is a typeless language, to infer types of input and output parameters,
-	* it relies on parsing the javadoc-style comment block associated with the given
-	* function. Usage of xmlrpc native types (such as datetime.dateTime.iso8601 and base64)
-	* in the @param tag is also allowed, if you need the php function to receive/send
-	* data in that particular format (note that base64 encoding/decoding is transparently
-	* carried out by the lib, while datetime vals are passed around as strings)
-	*
-	* Known limitations:
-	* - 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') and array('class', 'methodname') are ok too
-	* @param string $newfuncname (optional) name for function to be created
-	* @param array $extra_options (optional) array of options for conversion. valid values include:
-	*        bool  return_source when true, php code w. function definition will be returned, not evaluated
-	*        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 ---
-	*        bool  suppress_warnings  remove from produced xml any runtime warnings due to the php function being invoked
-	* @return false on error, or an array containing the name of the new php function,
-	*         its signature and docs, to be used in the server dispatch map
-	*
-	* @todo decide how to deal with params passed by ref: bomb out or allow?
-	* @todo finish using javadoc info to build method sig if all params are named but out of order
-	* @todo add a check for params of 'resource' type
-	* @todo add some trigger_errors / error_log when returning false?
-	* @todo what to do when the PHP function returns NULL? we are currently returning an empty string value...
-	* @todo add an option to suppress php warnings in invocation of user function, similar to server debug level 3?
-	* @todo if $newfuncname is empty, we could use create_user_func instead of eval, as it is possibly faster
-	* @todo add a verbatim_object_copy parameter to allow avoiding the same obj instance?

+     *
+     * Since php is a typeless language, to infer types of input and output parameters,
+     * it relies on parsing the javadoc-style comment block associated with the given
+     * function. Usage of xmlrpc native types (such as datetime.dateTime.iso8601 and base64)
+     * in the @param tag is also allowed, if you need the php function to receive/send
+     * data in that particular format (note that base64 encoding/decoding is transparently
+     * carried out by the lib, while datetime vals are passed around as strings)
+     *
+     * Known limitations:
+     * - 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') and array('class', 'methodname') are ok too
+     * @param string $newfuncname (optional) name for function to be created
+     * @param array $extra_options (optional) array of options for conversion. valid values include:
+     *        bool  return_source when true, php code w. function definition will be returned, not evaluated
+     *        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 ---
+     *        bool  suppress_warnings  remove from produced xml any runtime warnings due to the php function being invoked
+     * @return false on error, or an array containing the name of the new php function,
+     *         its signature and docs, to be used in the server dispatch map

+     * @todo add a check for params of 'resource' type
+     * @todo add some trigger_errors / error_log when returning false?
+     * @todo what to do when the PHP function returns NULL? we are currently returning an empty string value...
+     * @todo add an option to suppress php warnings in invocation of user function, similar to server debug level 3?

+     * Given an xmlrpc client and a method name, register a php wrapper function
+     * that will call it and return results using native php types for both
+     * params and results. The generated php function will return an xmlrpcresp
+     * object for failed xmlrpc calls
+     *
+     * Known limitations:
+     * - server must support system.methodsignature for the wanted xmlrpc method
+     * - for methods that expose many signatures, only one can be picked (we
+     *   could in principle 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 options 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 unspecified, 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
