You would need to do a foreach loop. The only problem is that if you want to make it dynamic and grab the data by itself without you telling it what to get. If not it means you would have to know exactly what you need and the structure of your results. But seeing that there is a pattern you can do some checks until you reach rows. For example ($array would be the variable that has the data you provided):

foreach ($array AS $arr) {
    // To make you function/check work faster,
    // before even entering to fetch for data
    // you can check if it has any data, else you
    // probably will end up with an error
    if (isset ($arr ['datas']) && $arr ['datas']) {
        foreach ($arr ['datas'] AS $data) {
            if (isset ($arr ['res']) && 0 < $arr ['res']) {
                // here is where it gets tricky because
                // from you example its either an array or an object
                // but the kool part about it is that you can convert an object into an array
                // or just leave it as is because the foreach will take care of it either way :)

                // first check it it is an object and convert if yes
                $row    = $arr ['rows'];

                if (!is_array ($row))
                    $row = (array)$row; // converting it to array is super easy :)

                foreach ($row AS $key=>$dat) {
                    // from here your result can either be another array or just data
                    // so you run the check once more
                    if (is_array ($dat)) {
                        foreach ($dat AS $k=>$d) {
                            echo "data for $k is $d";
                        }
                    }
                    else
                        echo "data for $key is $dat";
                }
            }
        }
    }
}
