在PHP中合并两个单独的数组
[英]Merge two separate arrays in php
问题描述
I have two arrays like below: 
我有两个像下面这样的数组：
array
'result1' =>
array
'entities' =>
array
0 =>
object(ElggUser)[979]
...
'count' => int 1
array
'result2' =>
array
'entities' =>
array
0 =>
object(ElggUser)[983]
...
1 =>
object(ElggUser)[986]
...
2 =>
object(ElggUser)[989]
...
3 =>
object(ElggUser)[992]
...
4 =>
object(ElggUser)[995]
...
5 =>
object(ElggUser)[998]
...
6 =>
object(ElggUser)[1001]
...
7 =>
object(ElggUser)[1004]
...
8 =>
object(ElggUser)[1007]
...
9 =>
object(ElggUser)[1010]
...
'count' => int 1453
So I have tried array_merge for this like array_merge($results1["result1"],$results2["result2"]); 所以我已经尝试过array_merge这样的array_merge($results1["result1"],$results2["result2"]); but I am getting the 2nd array as result how do it? 但是我得到第二个数组结果如何呢？ I am getting the result like: 我得到的结果是：
array
'entities' =>
array
0 =>
object(ElggUser)[983]
protected 'attributes' =>
array
...
protected 'url_override' => null
protected 'icon_override' => null
protected 'temp_metadata' =>

...
protected 'temp_annotations' =>

...

array
...
private 'valid' (ElggEntity) => boolean false
1 =>

You have a multidimensional array, so use array_merge_recursive : 您有一个多维数组，因此请使用array_merge_recursive ：
$result = array_merge_recursive($results1["result1"], $results2["result2"]);
for example: 例如：
$result1 = array("result1" => array("entities" => array(1, 2, 3)));
$result2 = array("result2" => array("entities" => array(4, 5, 6)));
var_dump(array_merge($result1["result1"], $result2["result2"]));
gives you 给你
array(1) {
'entities' =>
array(3) {
[0] =>
int(4)
[1] =>
int(5)
[2] =>
int(6)
}
}
while 而
var_dump(array_merge_recursive($result1["result1"], $result2["result2"]));
gives you the expected 给您期望
array(1) {
'entities' =>
array(6) {
[0] =>
int(1)
[1] =>
int(2)
[2] =>
int(3)
[3] =>
int(4)
[4] =>
int(5)
[5] =>
int(6)
}
}
