Here is my code:
$arr1 = ['p' => 2, 'pm' => 1];
$arr2 = ['p' => ''];
print_r(array_merge($arr1, $arr2));
And here is the current output:
Array
(
[p] =>
[pm] => 1
)
And here the expected result:
Array
(
[pm] => 1
[p] =>
)
Because the send array ($arr2) in array_merge() contains p key, so I want to put it in the end. Any idea how can I do that?
这是我的代码：
$ arr1 = [' p'=＆gt; 2，'pm'=＆gt; 1];
$ arr2 = ['p'=＆gt; ''];
print_r（array_merge（$ arr1，$ arr2））;
这里是当前输出：
Array
（
[p] =＆gt;
[pm] =＆gt; ; 1
）
这里是预期的结果：
Array
（
[pm ] =＆gt; 1
[p] =＆gt;
）
因为中的发送数组（ $ arr2 ） code> array_merge（）包含 p 键，所以我想把它放在最后。 知道我该怎么办？
Probably not the best solution, but I would remove the entries first and then add them again:
微信扫一扫print_r(array_merge(array_diff_key($arr1, $arr2), $arr2));
