Question

请看一下，我有2个数组array1和array2，我想比较这些数组，并需要array2中不存在的数组。我真的要解决这个问题，我正在开发应用程序。所以请帮我解决这个问题提前致谢。这是数组1

Array
(
    [0] => Array
        (
            [image_id] => 4
            [user_id] => 2
            [user_type] => user
            [canvas_id] => 1
            [canvas_mac] => 123.234.232.121
        )

    [1] => Array
        (
            [image_id] => 3
            [user_id] => 2
            [user_type] => user
            [canvas_id] => 1
            [canvas_mac] => 123.234.232.121
        )

    [2] => Array
        (
            [image_id] => 2
            [user_id] => 2
            [user_type] => user
            [canvas_id] => 1
            [canvas_mac] => 123.234.232.121
        )

    [3] => Array
        (
            [image_id] => 1
            [user_id] => 2
            [user_type] => user
            [canvas_id] => 1
            [canvas_mac] => 123.234.232.121
        )
)

这是array2

Array
(
    [0] => Array
        (
            [image_id] => 1
            [user_id] => 2
            [user_type] => user
            [canvas_id] => 1
            [canvas_mac] => 123.234.232.121
        )
    [1] => Array
        (
            [image_id] => 4
            [user_id] => 2
            [user_type] => user
            [canvas_id] => 1
            [canvas_mac] => 123.234.232.121
        )
)

我需要这样的结果

结果数组

Array(
    [0] => Array
        (
            [image_id] => 3
            [user_id] => 2
            [user_type] => user
            [canvas_id] => 1
            [canvas_mac] => 123.234.232.121
        )

    [1] => Array
        (
            [image_id] => 2
            [user_id] => 2
            [user_type] => user
            [canvas_id] => 1
            [canvas_mac] => 123.234.232.121
        )
)
