Question

我有四个数组，我想获得每个数组的公共元素。是否有一个函数可以让我比较多个数组并得到它们的共同元素？

[0] => Array
    (
        [0] => 121186
        [1] => MPE129
        [2] => MHB1
        [3] => 60000
        [4] => 2014-2015
        [5] => 1
    )

[1] => Array
    (
        [0] => 102147
        [1] => MPE129
        [2] => MHB1
        [3] => 60000
        [4] => 2014-2015
        [5] => 1
    )

[2] => Array
    (
        [0] => 130879
        [1] => MPE129
        [2] => MHB1
        [3] => 60000
        [4] => 2014-2015
        [5] => 1
    )

[3] => Array
    (
        [0] => 101768
        [1] => MPE129
        [2] => MHB1
        [3] => 60000
        [4] => 2014-2015
        [5] => 1
    )

Answer 1

array_intersect()

$intersect = array_intersect($array1,$array2,$array3);

如果你不知道你有多少个数组，那么就建立一个数组数组和用户call_user_func_array()

 $list = array();
 $list[] = $array1;
 $list[] = $array2;
 $list[] = $array3;
 $intersect = call_user_func_array('array_intersect',$list);

Answer 2

尝试使用array_intersect查找任何数组的公共元素。

$result = array_intersect($array[0],$array[1],$array[2])

Answer 3

尝试使用PHP自己的函数array_instersect()

在多个数组中查找常见元素
