Javascript 键与另一个数组匹配时关联数组中的更新值

当键与array2匹配时，我尝试更新array1值。和使用更新的值返回整个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
)

下面是我想要的结果

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

如何实现这一点？

您可以这样使用：

array_merge($array1, $array2)

---

您可以使用以下代码获得所需的输出：

  <?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)); 
?>

print_r（数组合并（$array1，$array2））；使用php的数组合并：数组合并（$array1，$array2）@团东玉，这是有效的。
