Use an array as an alternate method of sending/returning data to the second 
argument.

function escape($id, &$data) {
        if ( is_array($data) ) {
                foreach ( $data AS $k => $v ) {
                        escape($id, $v);
                        $data[$k] = $v;
                }
        } else {
                $data = mysql_real_escape_string($data, $id);
        }
}

This would handle any number of nested arrays/datasets.

Hope it helps.
