Question

我需要在第二级合并两个不同键名但数量相同的数组。

用户A = 102
用户B = 103

我想要的输出是数组3。

我尝试了很多变化来实现这一目标。

我最好的尝试类似于以下内容，但它破坏了我的关键名称：

$results = array();

foreach($arr1 as $key => $array)
{
  foreach($array as $user => $value)
   {
    $results[$user]['name'] = $value;   
   }
}

foreach($arr2 as $key => $array)
{   
  foreach($array as $user => $value)
   {
    $results[$user]['name2'] = $value;
   } 
}

数组1：

     Array
        (
            [usera] => Array
                (
                    [0] => Array
                        (
                            [user] => usera
                            [duration_s] => 15
                        )

                    [1] => Array
                        (
                            [user] => usera
                            [duration_s] => 9
                        )
                )
            [userb] => Array
                (
                   [2] => Array
                        (
                            [user] => userb
                            [duration_s] => 21  
                        )

                   [3] => Array
                        (
                            [user] => userb
                            [duration_s] => 19
                        )
                )

        )

数组2：

 Array
            (
                [102] => Array
                    (
                        [0] => Array
                            (
                                [user] => 102
                                [duration_s2] => 54
                            )

                        [1] => Array
                            (
                                [user] => 102
                                [duration_s2] => 378
                            )
                    )
                [103] => Array
                    (
                       [2] => Array
                            (
                                [usernr] => 103
                                [duration_s2] => 299
                            )

                       [3] => Array
                            (
                                [usernr] => 103
                                [duration_s2] => 110
                            )
                    )

            )

Answer 1

使用array_values()尝试以下代码：

<?php
$array1 = [
  'usera' => [
                0=> ['user' => 'usera','duration_s' => 15],
                1=> ['user' => 'usera','duration_s' => 9],
            ],
  'userb' => [
                2=> ['user' => 'usera','duration_s' => 15],
                3=> ['user' => 'usera','duration_s' => 9],
            ],

   ];

$array2 = [
  102 => [
     0=> ['usernr' => 102,'duration_s2' => 54],
     1=> ['usernr' => 102,'duration_s2' => 378]
  ],
 103 => [
    2=> ['usernr' => 103,'duration_s2' => 299],
    3=> ['usernr' => 103,'duration_s2' => 110]
 ],

];


$array2 = array_values($array2);
$array1 = array_values($array1);

foreach($array1 as $index=>$ar1){
 foreach ($ar1 as $index2=>$ar2){
     $array1[$index][$index2] = array_merge($ar2,$array2[$index][$index2]);
 }
}


print_r($array1);

Answer 2

要合并阵列，您还可以执行以下操作：

$index = 0;
foreach ($arr2 as $key => $value) { // changing the indexing of second array
    $arr3[$index] = $value;
    $index++;
}

$results = array();

$count = 0;
foreach ($arr1 as $index => $value) { // merging two array

    $total = 0;
    foreach ($value as $key => $val) {
        $merge_value = array_merge($val,$arr3[$count][$total]);
        $results[$index][$total] = $merge_value;
        $total++;
    }
    $count++;
}
print_r($results);

在此结果中，您的索引不会丢失。
