如何从JSON数组

打印单场数据我一直在使用laravel DB门面运行一个查询，它是返回一个JSON数组对象，但是当我想从JSON数组访问单个字段值是显示错误。如何从JSON数组

这是我的查询部分。

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

      return $dsale;

这是我的结果。

当我打印CLIENT_NAME $ dsale - > [ 'CLIENT_NAME'] [0]这样它的显示错误。

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

不是JSON，这是一个集合或数组的对象stdClass已经......只有当你试图用“echo”他们会看到JSON – lagbox

在阵列

..你需要先得到索引，那么获取对象..

例如：如果该项目是一个对象，做这样的..

$dsale[0]->client_name;

或者，如果该项目是一个数组类型，做这样的..

$dsale[0]['client_name']

我敢尝试。返回$ dsale [0] ['client_name'];但现在显示FatalThrowableError 不能使用类型为stdClass的对象作为数组此异常。 – Gabrielle

你有没有试过$ dsale [0] - > client_name; – ZeroOne

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