Question

我需要在PHP中合并两个数组，并且还必须匹配键

这是我的阵列

array1看起来像

[
    0 => "num",
    1 => "No",
    2 => "Name",
    3 => "Phone",
    4 => "Price",
    5 => "Date"
]

array2看起来像

[
    0 =>[
        "No" => "FR201605832",
        "Price" => 199.0,
        "Date" => "2016-09-01",
        "num" => "19",
        "Name" => "Tom",
        "Phone" => "0900123456"
    ],
    1 =>[
        "No" => "EC2016010100001",
        "Price" => 1680.0,
        "Date" => "2016-09-01",
        "num" => "1680",
        "Name" => "Ted",
        "Phone" => "0900321654"
    ]
]

这就是我想要的结果

[
    0 =>[
        "num" => "19",
        "No" => "FR201605832",
        "Name" => "Tom",
        "Phone" => "0900123456",
        "Price" => 199.0,
        "Date" => "2016-09-01",
    ],
    1 => [
        "num" => "1680",
        "No" => "EC2016010100001",
        "Name" => "Ted",
        "Phone" => "0900321654",
        "Price" => 1680.0,
        "Date" => "2016-09-01",
    ]
]

array1是用户对输入的excel标题进行重新排序，我可以获取重新排序请求，但不知道如何与值组合

Plz帮助我合并两个数组并导出预期结果，Thx

这是下一步

按array3重命名Result数组键

array3外观

数组：6 [▼

“ num” =>“ id”

“否” =>“ ECNo”

“名称” =>“用户”

“电话” =>“移动”

“价格” =>“总计”

“日期” =>“发薪日”

]

我尝试了

foreach（$ exportdata为＆$ val）{

$ val [$ values] = $ val [$ keys];

unset（$ val [$ value]）;

}

但是出现错误非法偏移类型

有什么好主意吗？

Answer 1

使用array_flip()和array_merge()来获得结果

$new = [];
foreach ($array as $value) {
  $new[] = array_merge(array_flip($order),$value);
}
dd($new);

您可以在创建第二个数组时订购该数组。无需再寻求帮助所以我想你的第二个数组数据有些不同，所以尝试这种方式

$new = [];
foreach ($array as $value) {
   if(isset($value['num'])) $data['num'] = $value['num'];
   if(isset($value['No'])) $data['No'] = $value['No'];
   if(isset($value['Name'])) $data['Name'] = $value['Name'];
   if(isset($value['Phone'])) $data['Phone'] = $value['Phone'];
   if(isset($value['Price'])) $data['Price'] = $value['Price'];
   if(isset($value['Date'])) $data['Date'] = $value['Date'];

   $new[] = $data;
}

Answer 2

这样做：

$modified = [];
foreach($parent as $i => $val) {
    foreach($child as $ci => $data) {
        $modified[$ci][$val] = $data[$val];
    }
}
echo "<pre>";print_r($modified);
