PHP如何将另一个文件中的Object添加到不同JSON的数组中

I want to move this object (in PHP)

(json1.json)

{
    "id": "TEST",
    "name": "TEST",
    "desc": "TEST",
    "image": "TEST",
    "package": "TEST",
    "version": "1.00",
    "picpath": "TEST",
    "desc_1": "ssss",
    "desc_2": "ssss",
    "ReviewStars": "5",
    "Size": "TEST",
    "Author": "TEST",
    "apptype": "222",
    "pv": "TEST",
    "main_icon_path": "TEST",
    "main_menu_pic": "TEST",
    "releaseddate": "2019-06-19",
}

into this array (json2.json)

{
  "packages": [
  {
      "id": "TEST",
      "name": "TEST",
      "desc": "TEST",
      "image": "TEST",
      "package": "TEST",
      "version": "1.00",
      "picpath": "TEST",
      "desc_1": "TEST",
      "desc_2": "TEST",
      "ReviewStars": "TEST",
      "Size": "",
      "Author": "TEST",
      "apptype": "TEST",
      "pv": "TEST",
      "main_icon_path": "TEST",
      "main_menu_pic": "TEST",
      "releaseddate": "5/03/2018"
    }
    ]
}

i want the final json to look like this

{
  "packages": [
  {
      "id": "TEST",
      "name": "TEST",
      "desc": "TEST",
      "image": "TEST",
      "package": "TEST",
      "version": "1.00",
      "picpath": "TEST",
      "desc_1": "TEST",
      "desc_2": "TEST",
      "ReviewStars": "TEST",
      "Size": "",
      "Author": "TEST",
      "apptype": "TEST",
      "pv": "TEST",
      "main_icon_path": "TEST",
      "main_menu_pic": "TEST",
      "releaseddate": "5/03/2018"
    },
{
    "id": "TEST",
    "name": "TEST",
    "desc": "TEST",
    "image": "TEST",
    "package": "TEST",
    "version": "1.00",
    "picpath": "TEST",
    "desc_1": "ssss",
    "desc_2": "ssss",
    "ReviewStars": "5",
    "Size": "TEST",
    "Author": "TEST",
    "apptype": "222",
    "pv": "TEST",
    "main_icon_path": "TEST",
    "main_menu_pic": "TEST",
    "releaseddate": "2019-06-19",
}

    ]
}

iv tried many solutions including this one

$datas[] = json_decode($json, true);

$datas[] = json_decode($json1, true);

$jsonData = json_encode($datas, JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES);

file_put_contents($jpath, $jsonData);```

<?php

$json1_str = '{
    "id": "TEST",
    "name": "TEST",
    "desc": "TEST",
    "image": "TEST",
    "package": "TEST",
    "version": "1.00",
    "picpath": "TEST",
    "desc_1": "ssss",
    "desc_2": "ssss",
    "ReviewStars": "5",
    "Size": "TEST",
    "Author": "TEST",
    "apptype": "222",
    "pv": "TEST",
    "main_icon_path": "TEST",
    "main_menu_pic": "TEST",
    "releaseddate": "2019-06-19"
}';

$json2_str = '{
  "packages": [
  {
      "id": "TEST",
      "name": "TEST",
      "desc": "TEST",
      "image": "TEST",
      "package": "TEST",
      "version": "1.00",
      "picpath": "TEST",
      "desc_1": "TEST",
      "desc_2": "TEST",
      "ReviewStars": "TEST",
      "Size": "",
      "Author": "TEST",
      "apptype": "TEST",
      "pv": "TEST",
      "main_icon_path": "TEST",
      "main_menu_pic": "TEST",
      "releaseddate": "5/03/2018"
    }
    ]
}';

$json1 = json_decode($json1_str, true);
$json2 = json_decode($json2_str, true);

$json2['packages'][] = $json1;

$jsonData = json_encode($json2, JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES);

echo $jsonData;

OUTPUT

    "packages": [
        {
            "id": "TEST",
