在PHP中为数组分配键和值

I have the following which assigns the values I need to an array in php

我有以下代码，它将我需要的值分配给php中的数组

 $resultsAr[$row['stop_name']][$row['route_long_name']][] = $row['arrival_time'];

However when I convert this to JSON it does not have any keys.

但是，当我将它转换为JSON时，它没有任何键。

echo json_encode($resultsAr);

e.g.

如。

{
Stop1: {
Destination1: [
"11:13",
"11:25"
],
Destination2: [
"11:15",
"11:27"
],
Destination3: [
"11:14",
"11:23",
"11:26"
]
},

They keys are actually the values. How can I assign key names to the array?

它们的键实际上是值。如何为数组分配键名?

Edited: the required JSON output would be keys with values:

已编辑:所需的JSON输出为键值:

[Stops => all stops] [destinations => destinations] [times => arrival times]

2 个解决方案

#1

You must be set key for array when you want to encode array to json

要将数组编码为json，必须为数组设置键

Example:

例子:

$i=0;
foreach ($rows as $row) {
       $resultsAr[$row['stop_name']][$row['route_long_name']][$i] = $row['arrival_time'];
       $i++;
}

#2

Can you try:

你可以尝试:

$obj = new stdClass();

$obj->name = "Stop1";
$obj->data = array(
    array("Destination1",array("11:13","11:25")),
    array("Destination2",array("11:13","11:25")),
    array("Destination3",array("11:13","11:25")),
    );

echo json_encode($obj);

On a side note Only numeric items can appear without quotation. json.org

在边注中，只有数字项可以不带引号地出现。json.org

Also to explain stdclass - What is stdClass in PHP?

还要解释stdclass——PHP中的stdclass是什么?
