实现whereNotIn的动态方式:

 $users = User::where('status',0)->get();
    foreach ($users as $user) {
                $data[] = $user->id;
            }
    $available = User::orderBy('name', 'DEC')->whereNotIn('id', $data)->get();

查询构建器:

DB::table(..)->select(..)->whereNotIn('book_price', [100,200])->get();

口才:

SomeModel::select(..)->whereNotIn('book_price', [100,200])->get();

$created_po = array();
     $challan = modelname::where('fieldname','!=', 0)->get();
     // dd($challan);
     foreach ($challan as $rec){
         $created_po[] = array_push($created_po,$rec->fieldname);
     }
     $data = modelname::whereNotIn('fieldname',$created_po)->orderBy('fieldname','desc')->with('modelfunction')->get();

查询构建器:

    DB::table('book_mast')
->select('book_name','dt_of_pub','pub_lang','no_page','book_price')
    ->whereNotIn('book_price', [100,200])->get();

口才:

BookMast::select('book_name','dt_of_pub','pub_lang','no_page','book_price')
->whereNotIn('book_price', [100,200])->get();

这是Laravel 7的工作变体

DB::table('user')                 
  ->select('id','name')
  ->whereNotIn('id', DB::table('curses')->where('id_user', $id)->pluck('id_user')->toArray())
  ->get();
