155 * @param args arguments to send (parameters to remote xmlrpc server)

159 * @param pass password for authentication
160 * @param secure secure. wether to use fsockopen_ssl. (requires special php build).
161 * @param output array. xml output options. can be null. details below:
163 * output_type: return data as either php native data types or xml
164 * encoded. if php is used, then the other values are ignored. default = xml
165 * verbosity: determine compactness of generated xml. options are
166 * no_white_space, newlines_only, and pretty. default = pretty
167 * escaping: determine how/whether to escape certain characters. 1 or
168 * more values are allowed. If multiple, they need to be specified as
169 * a sub-array. options are: cdata, non-ascii, non-print, and
170 * markup. default = non-ascii | non-print | markup
171 * version: version of xml vocabulary to use. currently, three are
172 * supported: xmlrpc, soap 1.1, and simple. The keyword auto is also
173 * recognized to mean respond in whichever version the request came
174 * in. default = auto (when applicable), xmlrpc
175 * encoding: the encoding that the data is in. Since PHP defaults to
176 * iso-8859-1 you will usually want to use that. Change it if you know
177 * what you are doing. default=iso-8859-1
