* @param int $options additional flags set by the streams API (or'ed together):
* - STREAM_USE_PATH If path is relative, search for the resource using the include_path.
* - STREAM_REPORT_ERRORS If this flag is set, you are responsible for raising errors using trigger_error() during opening of the stream.
* If this flag is not set, you should not raise any errors.
* @param string $opened_path full path of the file/resource, if the open was successfull and STREAM_USE_PATH was set
* @return boolean true if the ressource was opened successful, otherwise false
