$result = array();
        foreach ($productList->result_array() as $data) {
            $id = $data['id'];
            if (isset($result[$id])) {

                $result[$id]["liked"][] =$data["liked"];
            } else {
                $result[$id] = $data;

Let's say you have your array named $arr

$final = array();
foreach ($arr as $obj) {
    if (empty($final[$obj->id])) {
        $final[$obj->id] = $obj;
    } else {
        if (is_array($final[$obj->id]->liked)) {
            $final[$obj->id]->liked[] = $obj->liked;
        } else {
            $final[$obj->id]->liked = array(
                $final[$obj->id]->liked, $obj->liked
            );
        }
    }
}

Done in just one iteration and the result will be in the $final array.

EDITED:

And if after that you want the keys not to be the id just use array_values($final)
