在php中添加数组

Question

阵列已被全面覆盖,但仍然难以解决如何解决这个问题.我有两个数组,我想合并而不会覆盖重复的键,即

Array1
(
    [0] => 0
    [1] => 1
    [2] => 1
    [3] => 1
    [4] => 1
    [5] => 0
    [6] => 0
)

+ 

Array2
(
    [0] => 0
    [1] => 0
    [2] => 0
    [3] => 0
    [4] => 0
    [5] => 0
    [6] => 1
)

我理想的结果是

Array1 + Array2
(
    [0] => 0
    [1] => 1
    [2] => 1
    [3] => 1
    [4] => 1
    [5] => 0
    [6] => 1
)

我该怎么办？我尝试过使用+但是它会给出第一个数组作为结果

你想要做的是将两个数组映射到单个数组,包含两个相应值的最大值,如下所示:

$array1 = array(0, 1, 1, 1, 1, 0, 0);
$array2 = array(0, 0, 0, 0, 0, 0, 1);

$result = array_map('max', $array1, $array2);

它看起来像这样:

array(7) {
  [0]=>
  int(0)
  [1]=>
  int(1)
  [2]=>
  int(1)
  [3]=>
  int(1)
  [4]=>
  int(1)
  [5]=>
  int(0)
  [6]=>
  int(1)
}
