问题是我没有得到我想要的结果我想要比较这两个数组的元素并显示任何diff元素（如果存在）。

Answer 1

做这个简单的解决方案，尝试将数组添加到那里演示数组变量..

 $array1 = array(10, 15, 20, 25);
    $array2 = array(10, 15, 100, 150);
    $output = array_merge(array_diff($array1, $array2), array_diff($array2, $array1));


    // $output will be (20, 25, 100, 150);

Answer 2

array_diff只能以一种方式工作，为您提供第一个数组中不存在于另一个数组中的项目。

$result = array_merge(array_diff($dat, $input_array), array_diff($input_array, $dat));
