数组合并/插入不起作用

Question

现在这是我拥有的两个数组：

第一： “工作时间”： [ { “开幕”：“09:30”， “关闭”：“13:30”， "dayName": "星期天" }, { “开幕”：“”， “关闭”：“”， "dayName": "星期一" }, { “开幕”：“”， “关闭”：“”， "dayName": "星期二" }, { "开幕": "10:30", “关闭”：“06:30”， "dayName": "星期三" }, { “开幕”：“01:00”， "收盘": "08:00", "dayName": "星期四" }, { “开幕”：“”， “关闭”：“”， “dayName”：“星期五” }, { “开幕”：“”， “关闭”：“”， “dayName”：“星期六” }, ], 第二个： “折扣”： [ { "from_time": "13:00:00", "to_time": "14:50:00", “折扣”：“20”， "dayName": "星期三" }, { "from_time": "06:13:16", "to_time": "04:14:11", “折扣”：“20”， "dayName": "星期一" }, { "from_time": "05:10:15", "to_time": "06:10:17", “折扣”：“20”， "dayName": "星期二" }, { "from_time": "06:59:16", "to_time": "04:19:11", “折扣”：“20”， "dayName": "星期一" } ],

现在我想要这样的输出：

想要的输出： “工作时间”： { “开幕”：“”， “关闭”：“”， "dayName": "星期一" { "from_time": "06:13:16", "to_time": "04:14:11", “折扣”：“20”， "dayName": "星期一" }, { "from_time": "06:59:16", "to_time": "04:19:11", “折扣”：“20”， "dayName": "星期一" } }, 现在的输出： “工作时间”： [ { “开幕”：“09:30”， “关闭”：“13:30”， "dayName": "星期天" }, { “0”：{ "from_time": "06:13:16", "to_time": "04:14:11", “折扣”：“20”， "dayName": "星期一" }, “1”：{ "from_time": "06:59:16", "to_time": "04:19:11", “折扣”：“20”， "dayName": "星期一" }, “开幕”：“”， “关闭”：“”， "dayName": "星期一" }, { “0”：{ "from_time": "05:10:15", "to_time": "06:10:17", “折扣”：“20”， "dayName": "星期二" }, “开幕”：“”， “关闭”：“”， "dayName": "星期二" }, { “0”：{ "from_time": "13:00:00", "to_time": "14:50:00", “折扣”：“20”， "dayName": "星期三" }, "开幕": "10:30", “关闭”：“06:30”， "dayName": "星期三" }, { “开幕”：“01:00”， "收盘": "08:00", "dayName": "星期四" }, { “开幕”：“”， “关闭”：“”， “dayName”：“星期五” }, { “开幕”：“”， “关闭”：“”， “dayName”：“星期六” } ],

这是我的代码：

foreach ($returnDataAns['workingHours'] as $key => $value) { ＃ 代码... foreach ($returnDataAns['discount'] as $key2 => $value2) { ＃ 代码... if ($value['dayName'] == $value2['dayName']) { ＃ 代码... array_push($returnDataAns['workingHours'][$key], $value2); } } }

知道我该怎么做吗？我只想删除那些 0:1: 键！

这将为您提供所需的输出...

$arr1 = json_decode('[
        {
            "opening": "09:30",
            "closing": "13:30",
            "dayName": "sunday"
        },
        {
            "opening": "",
            "closing": "",
            "dayName": "monday"
        },
        {
            "opening": "",
            "closing": "",
            "dayName": "tuesday"
        },
        {
            "opening": "10:30",
            "closing": "06:30",
            "dayName": "wednesday"
        },
        {
            "opening": "01:00",
            "closing": "08:00",
            "dayName": "thursday"
        },
        {
            "opening": "",
            "closing": "",
            "dayName": "friday"
        },
        {
            "opening": "",
            "closing": "",
            "dayName": "saturday"
        }
    ]', true);

$arr2 = json_decode('[
        {
            "from_time": "13:00:00",
            "to_time": "14:50:00",
            "discount": "20",
            "dayName": "wednesday"
        },
        {
            "from_time": "06:13:16",
            "to_time": "04:14:11",
            "discount": "20",
            "dayName": "monday"
        },
        {
            "from_time": "05:10:15",
            "to_time": "06:10:17",
            "discount": "20",
            "dayName": "tuesday"
        },
        {
            "from_time": "06:59:16",
            "to_time": "04:19:11",
            "discount": "20",
            "dayName": "monday"
        }
    ]', true);

$finalArray = [];
foreach ($arr1 as $key => $day) {
    $subArray = [];
    foreach ($arr2 as $key2 => $dayData) {
        if ($day['dayName'] === $dayData['dayName']) {
            $subArray[] = $dayData;
        }
    }
    $finalArray[$key] = !empty($subArray) ? $finalArray[$key] = [$day, $subArray] : [$day];
}

echo '<pre>';
echo '$finalArray ' . print_r($finalArray, true);
echo '</pre>';
echo '<pre>';
echo '$finalArray json_encoded ' . print_r(json_encode($finalArray), true);
echo '</pre>';
exit;

这将为您提供来自json_encode 输出的以下 JSON 字符串：

            "dayName":"monday"

            "discount":"20",
            "dayName":"monday"
         }
      ]
   ],
   [  
      {  
         "opening":"",
         "closing":"",
         "dayName":"tuesday"
      },

]

Answer 2

我认为这会给你预期的输出。
我使用 array_combine 和 array_column 使第一个数组关联。
必须循环第二个数组以创建一个可以与第一个数组合并的数组。

最后我使用 array_values 来删除关联。

foreach($discount as $val){
    $discount2[$val['dayName']][] = $val;
}  

$res = array_values(array_merge_recursive(array_combine(array_column($WH, "dayName"), $WH), $discount2));

var_dump($res);
