如何合并两个关联多维阵列

Question

我必须数组：

Array
(
    [58812b9d2e069a0680000e06] => Array
        (
            [color] => #FF00FF
        )

)

和

Array
(
    [58812b9d2e069a0680000e06] => Array
        (
            [color] => #FF0000
        )

)

输出

array_merge($arr1, $arr2)

仅显示

$arr1

值。有人可以帮我吗？

Edit1-我想合并它们，即使它们具有相同的钥匙。

$ar1 = array("58812b9d2e069a0680000e06" => array("color" => "#FF00FF"));
$ar2 = array("58812b9d2e069a0680000e06" => array("color" => "#FF0000"));
$result = array_merge_recursive($ar1, $ar2);
print_r($result);

Answer 1

array_merge_recursive-递归合并两个或多个阵列

---

$array_1 = array("a"=>"demo 1", "b"=>"blogs");

$array_1 = array("z"=>"demo 2", "d"=>"articles");

print_r(array_merge_recursive($array_1, $array_2));
