我想把两个结果合并到一个Laravel中？

Question

I just tried to following code in this fetch form have some result and fetchformans have another result but i want both into one result. I have tried many times but not get both result into one.

$fetchform = DB::table('create_form')->where('f_id','=',$id)->get();
$uid=session()->get('uid');
$fetchformans = DB::table('submit_forms')->where([['f_id','=',$id],['t_id','=',$uid]])->get();
