想用子数组创建数组，这样我就可以遍历 JSON

Question

我正在尝试创建子数组，对此我很陌生。我的术语对我来说不是很好。我正在使用当前的 PHP 代码生成 JSON 数组。 JSON 输出如下。

foreach ($result as $row) {
    $points = $row['points'];
    $price = $points*20;
    $pricefrmt = "$".number_format ($price, 2);

    $return['resort'][$row['resortcode']][] = [
        'resort' => $row['resortname'],
        'roomcode' => $row['roomcode'],
        'room' => $row['roomname'],
        'view' => $row['viewname'],
        'checkin' => $checkin,
        'checkout' => $checkout,
        'available' => $row['available'],
        'price' => $pricefrmt,
        'points' => $row['points'],
        'sleeps' => $row['sleeps'],
        'sleepdetails' => $row['sleepdetails'],
        'bedding' => $row['bedding'],
        'sqfoot' => $row['sqfoot'],
        'roomdescription' => $row['roomdescription'],
        'amenities' => $row['amenities'],
        'layoutimg' => $row['layoutimg'],
        'roomimg' => $row['roomimg'],
        'roomimgthumb' => $row['roomimgthumb'],
    ];
}

echo json_encode($return);

下面的代码似乎创建了一个数组？与子数组？但是，手段：不给我一个数组编号吗？我想这不允许我浏览度假村？

SSR 下的所有内容都有 [0]、[1]、[2] 等。但是，一切都在使用：SSR、VGF 等都没有。我将使用循环来生成 HTML，但我似乎无法循环度假村部分。

{resort: {…}}
resort:
SSR: Array(7)
0: {resort: "Saratoga Springs Resort & Spa", roomcode: "TA", room: "Deluxe Studio", view: "Standard View", checkin: "2021-06-14", …}
1: {resort: "Saratoga Springs Resort & Spa", roomcode: "S9", room: "Deluxe Studio", view: "Preferred View", checkin: "2021-06-14", …}
2: {resort: "Saratoga Springs Resort & Spa", roomcode: "TB", room: "1-Bedroom Villa", view: "Standard View", checkin: "2021-06-14", …}
3: {resort: "Saratoga Springs Resort & Spa", roomcode: "SB", room: "1-Bedroom Villa", view: "Preferred View", checkin: "2021-06-14", …}
4: {resort: "Saratoga Springs Resort & Spa", roomcode: "TL", room: "2-Bedroom Lock-Off Villa", view: "Standard View", checkin: "2021-06-14", …}
5: {resort: "Saratoga Springs Resort & Spa", roomcode: "TC", room: "2-Bedroom Villa", view: "Standard View", checkin: "2021-06-14", …}
6: {resort: "Saratoga Springs Resort & Spa", roomcode: "TP", room: "2-Bedroom Lock-Off Villa", view: "Preferred View", checkin: "2021-06-14", …}
length: 7
__proto__: Array(0)
VGF: Array(9)
0: {resort: "Disney's Grand Floridian Resort & Spa", roomcode: "86", room: "Deluxe Studio", view: "Standard View", checkin: "2021-06-14", …}
1: {resort: "Disney's Grand Floridian Resort & Spa", roomcode: "81", room: "Deluxe Studio", view: "Lake View", checkin: "2021-06-14", …}
2: {resort: "Disney's Grand Floridian Resort & Spa", roomcode: "87", room: "1-Bedroom Villa", view: "Standard View", checkin: "2021-06-14", …}
3: {resort: "Disney's Grand Floridian Resort & Spa", roomcode: "82", room: "1-Bedroom Villa", view: "Lake View", checkin: "2021-06-14", …}
4: {resort: "Disney's Grand Floridian Resort & Spa", roomcode: "89", room: "2-Bedroom Lock-Off Villa", view: "Standard View", checkin: "2021-06-14", …}
5: {resort: "Disney's Grand Floridian Resort & Spa", roomcode: "88", room: "2-Bedroom Villa", view: "Standard View", checkin: "2021-06-14", …}
6: {resort: "Disney's Grand Floridian Resort & Spa", roomcode: "84", room: "2-Bedroom Lock-Off Villa", view: "Lake View", checkin: "2021-06-14", …}
7: {resort: "Disney's Grand Floridian Resort & Spa", roomcode: "83", room: "2-Bedroom Villa", view: "Lake View", checkin: "2021-06-14", …}
8: {resort: "Disney's Grand Floridian Resort & Spa", roomcode: "85", room: "3-Bedroom Grand Villa", view: "Lake View", checkin: "2021-06-14", …}

我觉得不需要它，而且我知道这个 javascript 不正确，但它让我知道我在看什么。我目前在这里没有初始的“resort”循环。

$(function getData() {
  $("#searchbtn").click(function () {
    var checkin = document.getElementById("start").value;
    var checkout = document.getElementById("end").value;
    var occupants = document.getElementById("party").value;
    $.ajax({
      url: "action.php",
      type: "POST",
      data: { checkin: checkin, checkout: checkout, occupants: occupants },
      dataType: "json",
      success: function (response) {
        console.log(response);
        console.log(response.resort.SSR[4].roomcode);
        searchresult(response);
      }
      });
      let searchresult = function(response) {
      let container = document.getElementById('resultsbox');
      let output = "";
      
        for (let j = 0; j < response.resort.SSR.length; j++) {
          output +=
            "<div class='roomresults'>"+
            "<div>" + response.resort.SSR[j].room + " - " + response.resort.SSR[j].view + "</div>" +
            "</div>";
        }
      
        $(container).html(output);
      }
});
});

感谢任何帮助，我只是在努力学习和理解。谢谢。

带有子数组的数组

<?php $data = array(
              'name'=>'ali',
              'lastname'=>'ahmadi',
              'emails'=> array(
                            'email1'=>'ali1@gmail.com',
                            'email2'=>'ali2@gmail.com',
                            'email3'=>'ali3@gmail.com',
                            )
              )?>

转 JSON

$toJSON = json_encode($data);
