好的，您可以在查询示例中使用两个页面进行处理
应该是这样的，然后您可以将其添加到数组中，然后对数组进行解码并像例例中那样进行回显：

//page source
$query ='select room_id,floor_id,flat_id,room_name,no_of_cots,cot_info,cot_id,cot_name,cot_status,flat_name,floor_name 
from table1 ,table2,table3,table4 where  table1.id=table2.id and table2.id=table3.id and table4.id=table3.id';

 $result = mysqli_query($conn,$query);
  $array_list=array();
  while($row = mysqli_fetch_array($result))
  {

  $array_list['room_id']=$row;
  $array_list['floor_id']=$row;
  $array_list['flat_id']=$row;
  $array_list['room_name']=$row;
  $array_list['cot_info']=$row;
  $array_list['cot_name']=$row;
  $array_list['cot_id']=$row;
  $array_list['cot_status']=$row;
  $array_list['flat_name']=$row;
  $array_list['floor_name']=$row;

    }


      $json_data = array(
                            "result"            => $array_list,
                            );
                            echo json_encode($json_data);



// page 2   
$content='{"result": [ { "room_id": "1", "floor_id": "1", "flat_id": "1", "room_name": "Room1", "no_of_cots": "4", "cot_info":[{"cot_id": "1", "cot_name": "COT1", "cot_status": "1"}, {"cot_id": "2", "cot_name": "COT2", "cot_status": "1"}], "flat_name": "Sumangali PG", "floor_name": "GroundFloor" }, { "room_id": "2", "floor_id": "1", "flat_id": "1", "room_name": "Room2", "no_of_cots": "2", "cot_info":[{"cot_id": "1", "cot_name": "COT1", "cot_status": "1"}, {"cot_id": "2", "cot_name": "COT2", "cot_status": "1"}], "flat_name": "Sumangali PG", "floor_name": "GroundFloor" } ] }';



$json=json_decode($content);

foreach($json->result as $row)
{
    print_r($row);



}
