我正在尝试使用PHP创建RESTful API.我无法以我以前看到的方式格式化它.会很感激一些指导.谢谢.

这是当前的JSON输出:

 [
    {
        "boardID": "12345",
        "MQ9": "673627",
        "MQ131": "87565",
        "MQ135": "67887",
        "longitude": "51.504425",
        "latitude": "-0.1291608",
        "time": "13:32",
        "date": "2018-03-14"
    },

这就是我想要实现的目标:

{
    "data": [
        {
        "boardID": "12345",
        "MQ9": "673627",
        "MQ131": "87565",
        "MQ135": "67887",
        "longitude": "51.504425",
        "latitude": "-0.1291608",
        "time": "13:32",
        "date": "2018-03-14"
   },

这是我的PHP:

<?php
  require 'connect.php';

  if(!$con){ 
  die('Could not connect: '.mysqli_error()); 
  } 

  $result = mysqli_query($con, "SELECT * FROM airQual"); 

  while($row = mysqli_fetch_assoc($result)
  { 
  $output[]=$row; 
  } 

  echo(json_encode($output, JSON_PRETTY_PRINT)); 

  mysqli_close($con);

  ?>
