在PHP中将新的键/值对添加到JSON中

Question

我的MySQL数据库的结果是我在PHP中使用json编码,结果如下:

[
    {
        "id": "8488",
        "name": "Tenby",
        "area": "Area1"
    },
    {
        "id": "8489",
        "name": "Harbour",
        "area": "Area1"
    },
    {
        "id": "8490",
        "name": "Mobius",
        "area": "Area1"
    }
] 

我想要做的是为该JSON添加一个新的键/值对,以便它将是:

[
    {
        "id": "8488",
        "name": "Tenby",
        "area": "Area1",
        "image": "1278.jpg"
    },
    {
        "id": "8489",
        "name": "Harbour",
        "area": "Area1",
        "image": "1279.jpg"
    },
    {
        "id": "8490",
        "name": "Mobius",
        "area": "Area1",
        "image": "1280.jpg"
    }
]

那我怎么能在PHP中做到这一点？

Answer 1

<?php

$data[0]['id']="8488";
$data[0]['name']="Tenby";
$data[0]['area']="Area1";

$data[1]['id']="8489";
$data[1]['name']="Harbour";
$data[1]['area']="Area1";

$data[2]['id']="8490";
$data[2]['name']="Mobius";
$data[2]['area']="Area1";

echo json_encode($data)."<br/>";

/*Add Image element (or whatever) into the array according to your needs*/

$data[0]['image']="1278.jpg";
$data[1]['image']="1279.jpg";
$data[2]['image']="1280.jpg";

echo json_encode($data);

?>
