php和从2数组中删除变量 - php and deleteing variable on from 2 array

Array1
(
    [0] => 14
    [1] => 9
    [2] => 10
    [3] => 11
)

Array2
(
    [0] => 8
    [1] => 9
    [2] => 10
    [3] => 11
    [4] => 12
    [5] => 13
    [6] => 14
    [7] => 15
    [8] => 16
    [9] => 17
    [10] => 18
    [11] => 19
    [12] => 20
    [13] => 21
    [14] => 22
    [15] => 23
    [16] => 24

一些函数删除数组2上的array1值并创建一个array3，结果是什么？

谢谢！

array_diff函数就是您想要的。我在哪里找到了这个函数，这要归功于Paulpro：https://stackoverflow.com/a/7241152/4912760.您案例的代码示例：

$array3 = array_diff($array2, $array1);
