              { 
                //dd(count($productsIds[$i]));    
                //$products=Product::all();

                 // $products = Product::where("id", $productsIds[$i])->first();
                   $products = Product::find($productsIds[$i]);
                    //echo $products ;
                    //dd($products);
                  if( !is_null($products))
                  {
                    $products->products_order = $i;
                    $products->save();
                  }
              }
          }
      }

      return redirect()->back();
  }

Try This:

 $products = Product::find($productsIds[$i])->get();

OR

 $products = Product::find($productsIds[$i])->all();

ONLY Single Record :

$products = Product::find($productsIds[$i])->one();
