如何使用PHP将一维数组合并为二维数组

Question

我有2个具有不同维度的数组，以及如何将我的一维数组合并为二维数组，这是我的2个数组的样子

这是我的二维数组

array (
0 => 
array (
'id' => 1,
'alias' => 'Anderson',
'location' => 'Semarang',
    'up' => 39144,
'status' => 'DOWN',
),

这是我的一维数组

 array (
  'last_accessed_by' => 1,
  'last_refresh' => '2018-10-29 00:21:39',
   'created_at' => '2018-10-29 00:21:39',
 )

这是我从合并数组中获得的期望

array (
  0 => 
  array (
    'id' => 1,
    'alias' => 'Anderson',
    'location' => 'Semarang',
    'up' => 39144,
    'status' => 'DOWN',
    'last_accessed_by' => 1,
    'last_refresh' => '2018-10-29 00:21:39',
    'created_at' => '2018-10-29 00:21:39',
  ),

Answer 1

您需要像这样合并第一个数组的[0]元素和整个第二个数组的元素...

代码：（ 演示 ）

$array1 = array (
    array (
        'id' => 1,
        'alias' => 'Anderson',
        'location' => 'Semarang',
        'up' => 39144,
        'status' => 'DOWN'
    )
);

$array2 =  array (
    'last_accessed_by' => 1,
    'last_refresh' => '2018-10-29 00:21:39',
    'created_at' => '2018-10-29 00:21:39'
);
$array1[0] = array_merge($array1[0], $array2);
// or because merging associative arrays, if you aren't scared of array union operators:
// $array1[0] += $array2;
//            ^^-- this merges the 2nd to [0] of the 1st without a function call

var_export($array1);

输出：

array (
  0 => 
  array (
    'id' => 1,
    'alias' => 'Anderson',
    'location' => 'Semarang',
    'up' => 39144,
    'status' => 'DOWN',
    'last_accessed_by' => 1,
    'last_refresh' => '2018-10-29 00:21:39',
    'created_at' => '2018-10-29 00:21:39',
  ),
)
