php - 找出php中两个数组的区别

Question

--$arr1----

Array
    (
        [0] => Array
            (
                [id] => 1
                [Name] => AAA
            )

        [1] => Array
            (
                [id] => 6
                [Name] => BBB
            )

    )

--$arr2---

Array
(
    [0] => Array
        (
            [id] => 1
            [Name] => AAA
        )

    [1] => Array
        (
            [id] => 6
            [Name] => BBB
        )

    [2] => Array
        (
            [id] => 46
            [Name] => CCC
        )

)

我希望最终结果如下。有没有人可以帮助我？

--最终结果--

Array
(
    [0] => Array
        (
            [id] => 46
            [Name] => CCC
        )

)

更新---

在这种情况下，array_diff($arr1,$arr2) 的结果为空。

Answer 1

最简单的方法是 Mark Ba​​ker 的解决方案或编写您自己的简单函数:

代码:

function arrdiff($a1, $a2) {
  $res = array();
  foreach($a2 as $a) if (array_search($a, $a1) === false) $res[] = $a;
  return $res;
  }

print_r(arrdiff($arr1, $arr2));

输出:

Array
(
  [0] => Array
    (
      [id] => 46
      [name] => CCC
    )
)
