Use implode to convert an array [1, 2, 3, 4,] into a string "1,2,3,4"


'country_id'=> implode(',', $request->input('country_id')[$i]??[]),

Your select input need to have a name attribute value ending with [] for it to be sent as an array.

example

<select name="country_id[1][]">
    //.....
</select>

EDIT:

Set your select input as this

@foreach ($pricing as $price)
<tr>
<td >{{$loop->iteration}}</td>
<input type="hidden" name="price_list[{{$loop->index}}]" value="{{$price->id}}">
<td >{{$price->type_name}}</td>
<td><input type="checkbox"  name="level_one[{{$loop->index}}]"  value="1"><input type="hidden"  name="level_one[{{$loop->index}}]"  value="0"></td>
<td><input type="checkbox"  name="level_two[{{$loop->index}}]"  value="1"><input type="hidden"  name="level_two[{{$loop->index}}]"  value="0"></td>
<td><input type="checkbox"  name="level_three[{{$loop->index}}]"  value="1"><input type="hidden"  name="level_three[{{$loop->index}}]"  value="0"></td>
<td><input type="checkbox"  name="level_four[{{$loop->index}}]"  value="1"><input type="hidden"  name="level_four[{{$loop->index}}]"  value="0"></td>
<td><input type="checkbox"  name="level_five[{{$loop->index}}]"  value="1"><input type="hidden"  name="level_five[{{$loop->index}}]"  value="0"></td>
<td><input type="checkbox"  name="level_six[{{$loop->index}}]"  value="1"><input type="hidden"  name="level_six[{{$loop->index}}]"  value="0"></td>
<td><input type="checkbox"  name="level_seven[{{$loop->index}}]"  value="1"><input type="hidden"  name="level_seven[{{$loop->index}}]"  value="0"></td>
<td><input type="checkbox"   name="level_eight[{{$loop->index}}]"  value="1"><input type="hidden"  name="level_eight[{{$loop->index}}]"  value="0"></td>
<td><input type="checkbox"  name="level_nine[{{$loop->index}}]"  value="1"><input type="hidden"  name="level_nine[{{$loop->index}}]"  value="0"></td>
<td><input type="checkbox"  name="level_ten[{{$loop->index}}]"  value="1"><input type="hidden"  name="level_ten[{{$loop->index}}]"  value="0"></td>
<td>
<select id="country_id" name="country_id[{{$loop->index}}][]"   multiple="multiple">
@foreach ($countrys as $country)
<option value="{{$country->id}}">{{$country->country_name}}</option>
@endforeach  
</select>

  $this-> validate($request,[
            'user_id'=>'required',
           
        ]); 
        $count = count($request->input('price_list',[]));
                     
       
        $permission = new Permission;
        for ($i=0; $i<$count; $i  ){
        // $country_id =$request->input('country_id',[])[$i];
        
        // print_r(implode(',', $request->input('country_id')));
       
        
             
        $data[] = array(
        'user_id' =>$request->input('user_id'),
        'price_list'=>$request->input('price_list')[$i], 
        'level_one'=>$request->input('level_one')[$i],

         );
         }
           
        // dd($data);
