在php中查找并删除多维数组中的Duplicate

Question

来自用户我得到了一个像这样的多维数组：

Array (
       [classCode] => Array ( 
                             [0] => class44 
                             [1] => class67
                             [2] => class34
                             [3] => class34
                             [4] => class44
                            ) 
       [className] => Array ( 
                             [0] => phy
                             [1] => mat 
                             [2] => chy
                             [3] => sci
                             [4] => phy
                            ) 
       ) 

我需要在数组中找到重复的值，还应该考虑＆＃39; [classCode]＆＃39;作为主键，应该返回如下所示的数组。

Array (
       [classCode] => Array ( 
                             [0] => class44 
                             [1] => class67
                             [2] => class34
                            ) 
       [className] => Array ( 
                             [0] => phy
                             [1] => mat 
                             [2] => chy
                            ) 
       )

使用array_map：

$result = array_map(function ($items) {
    return array_unique($items);
}, $your_array);
