156 * @param args arguments to send (parameters to remote xmlrpc server)
157 * @param debug debug level (0 none, 1, some, 2 more)
158 * @param timeout timeout in secs. (0 = never)
159 * @param user user name for authentication.
160 * @param pass password for authentication
161 * @param secure secure. wether to use fsockopen_ssl. (requires special php build).
162 * @param output array. xml output options. can be null. details below:
164 * output_type: return data as either php native data types or xml
165 * encoded. if php is used, then the other values are ignored. default = xml
166 * verbosity: determine compactness of generated xml. options are
167 * no_white_space, newlines_only, and pretty. default = pretty
168 * escaping: determine how/whether to escape certain characters. 1 or
169 * more values are allowed. If multiple, they need to be specified as
170 * a sub-array. options are: cdata, non-ascii, non-print, and
171 * markup. default = non-ascii | non-print | markup
172 * version: version of xml vocabulary to use. currently, three are
173 * supported: xmlrpc, soap 1.1, and simple. The keyword auto is also
174 * recognized to mean respond in whichever version the request came
175 * in. default = auto (when applicable), xmlrpc
176 * encoding: the encoding that the data is in. Since PHP defaults to
177 * iso-8859-1 you will usually want to use that. Change it if you know
178 * what you are doing. default=iso-8859-1
