多维数组按对象推送无法正常工作

Question

我有一个需要以特定方式格式化的数组，但它正在为其中一个对象生成一个随机密钥。请参阅下面的代码

$temp = [
[
    "UID" => "100",
    "UPID" => "001",
    "PID" => "test1"
],
[
    "UID" => "1001",
    "UPID" => "002",
    "PID" => "test1"
]
];

$child = [];
        foreach ($temp as $key => $value) {
            $child[$value['UID']][$key]['UPID'] = $value['UPID'];
            $child[$value['UID']][$key]['PID'] = $value['PID'];
        }
 $oldParentData['childUserProductDetail'] = $child;
echo "<pre>";

$result = json_encode($oldParentData, true);
print_r($result);

my expected output

    {
  "childUserProductDetail": {
    "100": [
      {
        "UPID": "001",
        "PID": "test1"
      }
    ],
    "1001": [
       {
        "UPID": "002",
        "PID": "test1"
      }
    ]
  }
}

getting output

{

"childUserProductDetail": {
    "100": [
      {
        "UPID": "001",
        "PID": "test1"
      }
    ],
    "1001": {
      "1": {                                // See 1 as key here, that is unwanted
        "UPID": "002",
        "PID": "test1"
      }
    }
  }
}

这里我不知道第二次数组没有创建并且 1 来自 where.kindly 任何人都根据我的预期答案更新我的代码。

Answer 1

只是零钱。删除正在创建索引的 [Key] 部分，例如 0、1。

所以即使对于 UID = 1001 这是第一条记录，但由于循环键位于 1，我们需要将其删除。

foreach ($temp as $key => $value) {
    $child[$value['UID']][] = ['UPID' => $value['UPID'], 'PID'=> $value['PID']];
}
