Php 如何比较两个阵列并获得不适合阵列的数据

我现在有两个数组，我怎样才能得到两个数组之间的差异

foreach($test1 as $array)
{
    if (!isset($result[$array["id"]])) $result[$array["id"]] = $array["date"];
}
foreach ($result as $id => $date) {
    $new1[] = array("id" => $id, "date" => $date);
}

给我这个输出：

Array ( [0] => Array ( [id] => 47523 [date] => 11-02-13 05:36:32 ) [1] => Array ( [id] => 42415 [date] => 12-02-13 13:56:48 ) 

Array ( [0] => Array ( [id] => 47523 [date] => 12-02-13 14:22:14 ) [1] => Array ( [id] => 42135[date] => 02-02-13 14:51:42 )

给我这个输出：

Array ( [0] => Array ( [id] => 47523 [date] => 11-02-13 05:36:32 ) [1] => Array ( [id] => 42415 [date] => 12-02-13 13:56:48 ) 

Array ( [0] => Array ( [id] => 47523 [date] => 12-02-13 14:22:14 ) [1] => Array ( [id] => 42135[date] => 02-02-13 14:51:42 ) 

现在我想比较它们，这样我就可以得出差异：我希望预期输出如下所示：

Array ( [0] => Array ( [id] => 42415 [date] => 12-02-13 13:56:48 ) [1] => Array ( [id] => 42135[date] => 02-02-13 14:51:42) 

使用

排列
(
[1] =>蓝色
)

您尝试过什么？PHP中内置了很多

array_xxx（）

函数；你有没有试过？你得到了什么结果？几乎所有的结果/我刚更新了我的问题那又怎样？把我的答案贴在这里？
