如何從JSON數組

打印單場數據我一直在使用laravel DB門面運行一個查詢，它是返回一個JSON數組對象，但是當我想從JSON數組訪問單個字段值是顯示錯誤。如何從JSON數組

這是我的查詢部分。

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

      return $dsale;

這是我的結果。

當我打印CLIENT_NAME $ dsale - > [ 'CLIENT_NAME'] [0]這樣它的顯示錯誤。

嘗試：'$ dsale [0] [ 'CLIENT_NAME']' - HTTPS：//3v4l.o RG/nCQuV –

不是JSON，這是一個集合或數組的對象stdClass已經......只有當你試圖用「echo」他們會看到JSON – lagbox

在陣列

..你需要先得到索引，那麼獲取對象..

例如：如果該項目是一個對象，做這樣的..

$dsale[0]->client_name;

或者，如果該項目是一個數組類型，做這樣的..

$dsale[0]['client_name']

我敢嘗試。返回$ dsale [0] ['client_name'];但現在顯示FatalThrowableError 不能使用類型爲stdClass的對象作爲數組此異常。 – Gabrielle

你有沒有試過$ dsale [0] - > client_name; – ZeroOne

謝謝，$ dsale [0] - > client_name;這是完美的作品。 – Gabrielle
