当键与另一个数组匹配时，更新关联数组中的值

Question

当键与array2匹配时，我试图更新array1的值。 并返回具有更新值的整个array1

$array1 =array("subj1"=>"10","subj2"=>"20","subj3"=>"30","subj4"=>"40","subj5"=>"36","subj6"=>"85");
print_r($array1);
Array
(
    [subj1] => 10
    [subj2] => 20
    [subj3] => 30
    [subj4] => 40
    [subj5] => 36
    [subj6] => 85
)
$array2=array("subj1"=>"110","subj2"=>"130");
print_r($array2);
Array
(
    [subj1] => 110
    [subj2] => 130
)

以下是我想要的结果。

Array
(
    [subj1] => 110
    [subj2] => 130
    [subj3] => 30
    [subj4] => 40
    [subj5] => 36
    [subj6] => 85
)

我该如何实现？

Answer 1

您可以这样使用array_merge ：

array_merge($array1, $array2)

Answer 2

您可以使用以下代码获取所需的输出：

  <?php
$array1 =array("subj1"=>"10","subj2"=>"20","subj3"=>"30","subj4"=>"40","subj5"=>"36","subj6"=>"85");
print_r($array1);
echo "<br>";
$array2=array("subj1"=>"110","subj2"=>"130");
print_r($array2);
echo "<br>";
print_r(array_merge($array1, $array2)); 
?>
