Php 合并2个Json结果并计算特定值

我有许多JSON，例如：

第1项：

{
    "countries_views": [
        {
            "thecount": "563",
            "country": "Greece"
        },
        {
            "thecount": "48",
            "country": "United States"
        },
        {
            "thecount": "11",
            "country": "Luxembourg"
        },
        {
            "thecount": "7",
            "country": "Germany"
        },
        {
            "thecount": "6",
            "country": "Cyprus"
        },
        {
            "thecount": "2",
            "country": "India"
        },
        {
            "thecount": "2",
            "country": "France"
        },
        {
            "thecount": "2",
            "country": "United Kingdom"
        },
        {
            "thecount": "1",
            "country": "Nigeria"
        },
        {
            "thecount": "1",
            "country": "Russia"
        }
    ]
}

{
    "countries_views": [
        {
            "thecount": "1037",
            "country": "Greece"
        },
        {
            "thecount": "17",
            "country": "United States"
        },
        {
            "thecount": "17",
            "country": "Cyprus"
        },
        {
            "thecount": "12",
            "country": "Germany"
        },
        {
            "thecount": "11",
            "country": ""
        },
        {
            "thecount": "4",
            "country": "United Kingdom"
        },
        {
            "thecount": "4",
            "country": "Australia"
        },
        {
            "thecount": "2",
            "country": "Belgium"
        },
        {
            "thecount": "1",
            "country": "Russia"
        },
        {
            "thecount": "1",
            "country": "Argentina"
        }
    ]
}

第2项：

{
    "countries_views": [
        {
            "thecount": "563",
            "country": "Greece"
        },
        {
            "thecount": "48",
            "country": "United States"
        },
        {
            "thecount": "11",
            "country": "Luxembourg"
        },
        {
            "thecount": "7",
            "country": "Germany"
        },
        {
            "thecount": "6",
            "country": "Cyprus"
        },
        {
            "thecount": "2",
            "country": "India"
        },
        {
            "thecount": "2",
            "country": "France"
        },
        {
            "thecount": "2",
            "country": "United Kingdom"
        },
        {
            "thecount": "1",
            "country": "Nigeria"
        },
        {
            "thecount": "1",
            "country": "Russia"
        }
    ]
}

{
    "countries_views": [
        {
            "thecount": "1037",
            "country": "Greece"
        },
        {
            "thecount": "17",
            "country": "United States"
        },
        {
            "thecount": "17",
            "country": "Cyprus"
        },
        {
            "thecount": "12",
            "country": "Germany"
        },
        {
            "thecount": "11",
            "country": ""
        },
        {
            "thecount": "4",
            "country": "United Kingdom"
        },
        {
            "thecount": "4",
            "country": "Australia"
        },
        {
            "thecount": "2",
            "country": "Belgium"
        },
        {
            "thecount": "1",
            "country": "Russia"
        },
        {
            "thecount": "1",
            "country": "Argentina"
        }
    ]
}

等等！我需要做的是用PHP将这些数据合并到一个数组中，我需要添加重复的值。最终结果应该如下所示：

{
    "countries_views": [
        {
            "thecount": "**1600**",
            "country": "Greece"
        },
        {
            "thecount": "**65**",
            "country": "United States"
        },
        etcetcetc
    ]
}

---

首先解析JSON数据，我们只需遍历数组来找到重复项并将其相加

<?php

// emit the code of parsing json. (see function json_decode)

$arr1 = [
    (object)['thecount' => 563, 'country' => 'Greece'],
    (object)['thecount' => 12, 'country' => 'US'],
    (object)['thecount' => 15, 'country' => 'UK'],
];

$arr2 = [
    (object)['thecount' => 1563, 'country' => 'Greece'],
    (object)['thecount' => 152, 'country' => 'CN'],
];

foreach ($arr1 as $each) {
    $exists = false;
    foreach ($arr2 as &$e) {
        if ($e->country == $each->country) {
            $e->thecount += $each->thecount;
            $exists = true;
        }
    }
    if (!$exists) {
        array_push($arr2, $each);
    }
}

$res = $arr2;

var_dump($res);

显示你的代码：）然后我可以试着帮你你好，阿德里安！我不知道该怎么做，我尝试过：json_解码和json_编码进行合并，但都没有达到我所需要的程度。首先，使用
json_解码（$json_object，true）
获取有效的php数组。然后，您必须创建一个函数，以您想要的方式合并解码的数组。
