在PHP中循环访问多维数组，并按组显示内容

对于任何重复内容，我深表歉意.我搜索和阅读了其他问题，但没有找到任何问题.我有一个来自JSON请求的多维数组，我希望遍历该数组并根据其中一个值按组显示其内容.这是我的JSON:

{
    "response": {
        "error": false,
        "message": "",
        "total_items": 6,
        "items": [
            {
                "id": 1001,
                "server_name": "server001.test.com",
            },
            {
                "id": 1001,
                "server_name": "server002.test.com",
            },
            {
                "id": 1002,
                "server_name": "server001.test.com",
            },
            {
                "id": 1002,
                "server_name": "server002.test.com",
            },
            {
                "id": 1002,
                "server_name": "server003.test.com",
            },
            {
                "id": 1003,
                "server_name": "server001.test.com",
            },
            {
                "id": 1003,
                "server_name": "server002.test.com",
            },
            {
                "id": 1003,
                "server_name": "server003.test.com",
            },
            {
                "id": 1004,
                "server_name": "server004.test.com",
            },
        ]
    }
}

到目前为止，我的 idea 是:

<?php
$json = '{
    "response": {
        "error": false,
        "message": "",
        "total_items": 6,
        "items": [
            {
                "id": 1001,
                "server_name": "server001.test.com"
            },
            {
                "id": 1001,
                "server_name": "server002.test.com"
            },
            {
                "id": 1002,
                "server_name": "server001.test.com"
            },
            {
                "id": 1002,
                "server_name": "server002.test.com"
            },
            {
                "id": 1002,
                "server_name": "server003.test.com"
            },
            {
                "id": 1003,
                "server_name": "server001.test.com"
            },
            {
                "id": 1003,
                "server_name": "server002.test.com"
            },
            {
                "id": 1003,
                "server_name": "server003.test.com"
            },
            {
                "id": 1004,
                "server_name": "server004.test.com"
            }
        ]
    }
}';

$array = json_decode($json, true);

if ($array) {
    $items = $array['response']['items'];
}

foreach ($array as $item) {

    foreach ($items as $key) {
        $id = $items[0]['id'];
        $server_name = $items[0]['server_name'];
        echo "| $id | $server_name | <br/>";
    }

}

?>

我的输出是:

| 1001 | server001.test.com |
| 1001 | server001.test.com |
| 1001 | server001.test.com |
| 1001 | server001.test.com |
| 1001 | server001.test.com |
| 1001 | server001.test.com |
| 1001 | server001.test.com |
| 1001 | server001.test.com |
| 1001 | server001.test.com |

但我预计会是这样的:

| 1001 | server001.test.com |
|      | server002.test.com |
| 1002 | server001.test.com |
|      | server002.test.com |
|      | server003.test.com |
| 1003 | server001.test.com |
|      | server002.test.com |
|      | server003.test.com |
| 1004 | server004.test.com |
