json 배열에서 단일 필드 데이터를 인쇄하는 방법

Question

laravel DB facade를 사용하여 쿼리를 실행하고 json 배열 객체를 반환하지만 json 배열에서 단일 필드 값에 액세스하려고 할 때 오류가 발생합니다.

내 검색어 부분은 다음과 같습니다.

$dsale=DB::table('directsales') 
      ->join('clients','directsales.client_id','=','clients.id') 
      ->join('products','directsales.product_id','=','products.id') 
      ->select('clients.client_name','clients.addr','directsales.*','products.name') 
      ->where('directsales.client_id','=',$client_id) 
      ->whereBetween('directsales.issue_date',[$fromdate,$todate]) 
      ->distinct() 
      ->get(); 

      return $dsale; 

이것은 내 결과입니다. 내가 클라이언트 _ $ dsale 인쇄 할 때
