Returning Data when no Results

Hi Fist of all Im Completely New to Laravel i have a function in my Controller like this

    public function getSinglePurchase($id){
            return DB::table('purchasespayment')
                    ->where("fk_purchases","=",$id)
                    ->orderBy('date', 'desc')->first();
     }
     public function show($id){
        $purchase_info = $this->getSinglePurchase($id);
        return view('purchase.view',compact('purchase_info');
    }

and when i return this data to view if there is data on return my view is working fine. and when there is no data for example my view file looks like this

{{ purchase_info.amount }}

whenever my controller returns nothing to view i get following error "Trying to get property 'amount ' of non-object"

I Managed to Fixe that error like following

@if (!empty($purchase_info)) 
    {{ $purchase_info->amount}}
  @endif 

this method working fine but i have almost 10 to 15 items to get like this do i need to check !empty method everytime or is there any easy way to get or check empty values via Controller. Please Advice
