json配列からの単一フィールドデータの出力方法

Question

laravel DBファサードを使用してクエリを実行しました.json配列オブジェクトを返しますが、json配列から単一フィールド値にアクセスする場合はエラーが表示されます。

ここは私のクエリの部分です。

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

      return $dsale; 

これは私の結果です。

Answer 1

..あなたがオブジェクトを取得し、その後、最初のインデックスを取得する必要があります。..

例：アイテムがオブジェクトである 場合は、次のように行う。..

$dsale[0]->client_name;

またはアイテムが配列型である場合には、次のように行う。..

$dsale[0]['client_name']
