PHP关联数组交集返回两个元素而不是一个元素

Question

我有两个关联数组，如下所示

    Array
(

    [0] => Array
        (
            [description] => aaaaaa
            [value] => 11111
            [id] => 14
        )

    [1] => Array
        (
            [description] => dddddd
            [value] => 44444
            [id] => 0
        )

)




Array
(

    [0] => Array
        (
            [id] => 14
            [value] => 11111
            [description] => aaaaaa
        )

    [1] => Array
        (
            [id] => 15
            [value] => 222222
            [description] => bbbbbb
        )

    [2] => Array
        (
            [id] => 16
            [value] => 333333
            [description] => cccccc
        )

)

我得到的结果是

Array
(

    [0] => Array
        (
            [description] => aaaaaa
            [value] => 11111
            [id] => 14
        )

    [1] => Array
        (
            [description] => dddddd
            [value] => 44444
            [id] => 0
        )

)

注意dddd在第一个数组中可用，但在第二个数组中不可用。

我正在使用array_intersect_assoc( $array1, $array2 )功能。 请帮忙。返回这样的结果是不合逻辑的

Answer 1

使用以下代码

$intersect = array_uintersect($arr1, $arr2, 'compareDeepValue');
 print_r($intersect);

 function compareDeepValue($val1, $val2)
 {
  return strcmp($val1['value'], $val2['value']);
 }

Answer 2

如果您将启用php通知，您将看到下一个

Notice: Array to string conversion
