PHP-比较两个数组
[英]PHP - Compare two arrays
问题描述
These are my 2 arrays: 
这些是我的2个数组：
Array
(
[25] => Array
(
[items_to_give] => Array
(
[0] => Array
(
[xx] => xx
[xx] => xx
)
)
[items_to_get] => Array
(
[0] => Array
(
[xx] => xx
[xx] => xx
)
)
)
[26] => Array
(
[items_to_give] => Array
(
[0] => Array
(
[xx] => xx
[xx] => xx
)
)
[items_to_get] => Array
(
[0] => Array
(
[xx] => xx
[xx] => xx
)
)
)
[36] => Array
(
[items_to_give] => Array
(
[0] => Array
(
[xx] => xx
[xx] => xx
)
)
[items_to_get] => Array
(
[0] => Array
(
[xx] => xx
[xx] => xx
)
)
)
)
and 和
Array
(
[25] => Array
(
[items_to_give] => Array
(
[0] => Array
(
[xx] => xx
[xx] => xx
)
)
[items_to_get] => Array
(
[0] => Array
(
[xx] => xx
[xx] => xx
)
)
)
[26] => Array
(
[items_to_give] => Array
(
[0] => Array
(
[xx] => xx
[xx] => xx
)
)
[items_to_get] => Array
(
[0] => Array
(
[xx] => xx
[xx] => xx
)
)
)
[30] => Array
(
[items_to_give] => Array
(
[0] => Array
(
[xx] => xx
[xx] => xx
)
)
[items_to_get] => Array
(
[0] => Array
(
[xx] => xx
[xx] => xx
)
)
)
)
And now i want to compare these arrays and return all arrayitems which are contained in both arrays. 现在我想比较这些数组并返回两个数组中包含的所有arrayitem。 In the example these are [25] and [26]. 在示例中，这些是[25]和[26]。
So the returned array should look like this (As i said [25] and [26] are contained in both arrays so its returned): 因此，返回的数组应如下所示（正如我所说的[25]和[26]都包含在两个数组中，因此返回了）：
Array
(
[25] => Array
(
[items_to_give] => Array
(
[0] => Array
(
[xx] => xx
[xx] => xx
)
)
[items_to_get] => Array
(
[0] => Array
(
[xx] => xx
[xx] => xx
)
)
)
[26] => Array
(
[items_to_give] => Array
(
[0] => Array
(
[xx] => xx
[xx] => xx
)
)
[items_to_get] => Array
(
[0] => Array
(
[xx] => xx
[xx] => xx
)
)
)
)
What i already tried: 我已经尝试过的
$result = array_map("unserialize", array_intersect($this->serialize_array_values($array1),$this->serialize_array_values($array2)));
function serialize_array_values($arr){
foreach($arr as $key=>$val){
sort($val);
$arr[$key]=serialize($val);
}
return $arr;
}
But this returns the array in the wrong format. 但这会以错误的格式返回数组。 The [items_to_give] and [items_to_get] are getting converted to the index [0] and [1] which is undesirable. [items_to_give]和[items_to_get]被转换为索引[0]和[1]，这是不希望的。
I want the array to stay as he is when returned that means i need [items_to_give] and [items_to_get] instead of indexes [0] and [1] 我希望数组在返回时保持原样 ，这意味着我需要[items_to_give]和[items_to_get]而不是索引[0]和[1]
What are other possible solutions? 还有哪些其他可能的解决方案？ Thanks for solutions. 感谢您的解决方案。

Try this function: 试试这个功能：
function my_array_diff($arr1, $arr2)
{
$res = array();
foreach ($arr1 as $val1) {
$val1 = serialize($val1);
foreach ($arr2 as $key2 => $val2) {
if (serialize($val2) == $val1) {
$res[$key2] = $val2;
}
}
}
return $res;
}
