重建阵列以从第二个阵列添加密钥

如何使用Array1和Array2来获取想要的结果？重建阵列以从第二个阵列添加密钥

数组1

array(
    (int) 0 => '37', 
    (int) 1 => '38' 
)

数组2

array(
    (int) 0 => array(
     'ParentKey' => array(
      'ChildKey1' => '1', 
      'ChildKey2' => '2' 
     ) 
    ), 
    (int) 1 => array(
     'ParentKey' => array(
      'ChildKey1' => '1', 
      'ChildKey2' => '1' 
     ) 
    ) 
)

通缉的结果

array(
    (int) 0 => array(
     'ParentKey' => array(
      'Array1Key' => 37, 
      'ChildKey1' => '1', 
      'ChildKey2' => '2' 
     ) 
    ), 
    (int) 1 => array(
     'ParentKey' => array(
      'Array1Key' => 37, 
      'ChildKey1' => '1', 
      'ChildKey2' => '1' 
     ) 
    ) 
    (int) 2 => array(
     'ParentKey' => array(
      'Array1Key' => 38, 
      'ChildKey1' => '1', 
      'ChildKey2' => '2' 
     ) 
    ), 
    (int) 3 => array(
     'ParentKey' => array(
      'Array1Key' => 38, 
      'ChildKey1' => '1', 
      'ChildKey2' => '1' 
     ) 
    ) 
)

我已经试过几件事情，但是这让我最接近...

PHP

$data = array(); 
foreach($Array1 as $id) 
{ 
    foreach($Array2 as $Array1Result) 
    { 
     $data[]['ParentKey'] = array(
      'Array1Key' => $id, 
      $Array1Result['ParentKey'] 
     ); 
    } 
}

结果

array(
    (int) 0 => array(
    'ParentKey' => array(
     'Array1Key' => '37', 
     (int) 0 => array(
      'ChildKey1' => '1', 
      'ChildKey2' => '2' 
     ) 
    ) 
), 
    (int) 1 => array(
    'ParentKey' => array(
     'Array1Key' => '37', 
     (int) 0 => array(
      'ChildKey1' => '1', 
      'ChildKey2' => '1' 
     ) 
    ) 
), 
    (int) 2 => array(
    'ParentKey' => array(
     'Array1Key' => '38', 
     (int) 0 => array(
      'ChildKey1' => '1', 
      'ChildKey2' => '2' 
     ) 
    ) 
), 
    (int) 3 => array(
    'ParentKey' => array(
     'Array1Key' => '38', 
     (int) 0 => array(
      'ChildKey1' => '1', 
      'ChildKey2' => '1' 
     ) 
    ) 
) 
)

，问题是... – useyourillusiontoo

替换'阵列（ 'Array1Key'=> $ ID，$ Array1Result [ 'ParentKey']）与'array_merge（阵列（ 'Array1Key'=> $ ID）'， $ Array1Result ['ParentKey']）' –

@CharlotteDunois几乎没有。谢谢！我只需要在'$ data [] ['ParentKey'] =' – Draven

你究竟是什么你做什么。你把一个数组放入数组中。但是你需要将两个数组合并在一起。第一个是Array1Key，第二个是旧数组。你可以通过array_merge来实现。

$data = array(); 
foreach($Array1 as $id) 
{ 
    foreach($Array2 as $Array1Result) 
    { 
     $data[]['ParentKey'] = array_merge(
      array('Array1Key' => $id), 
      $Array1Result['ParentKey'] 
     ); 
    } 
}
