删除多维数组重复值 [英] Remove duplicate value in multidimensional array

问题描述

所有
我想从这个数组删除重复值

 阵列
（
    [0] =＆GT;排列
        （
            [0] =＆GT;阿贾伊帕特尔
            [1] =＆GT;标签1
        ）    [1] =＆GT;排列
        （
            [0] =＆GT;标签1
            [1] =＆GT;标签3
        ）    [2] =＆GT;排列
        （
        ）    [3] =＆GT;排列
        （
        ）    [4] =＆GT;排列
        （
        ））
 

我想从这个解决方案<一个href=\"http://stackoverflow.com/questions/307674/how-to-remove-duplicate-values-from-a-multi-dimensional-array-in-php\">How从PHP中多维数组中删除重复值

$结果2 = array_map（反序列化，array_unique（array_map（连载，$结果2）））;

但我觉得有什么错在这里，我得到这个作为结果。

 阵列
（
    [0] =＆GT;排列
        （
            [0] =＆GT;阿贾伊帕特尔
            [1] =＆GT;标签1
        ）    [1] =＆GT;排列
        （
            [0] =＆GT;标签1
            [1] =＆GT;标签3
        ）    [2] =＆GT;排列
        （
        ））
 

我要的是

 阵列
            （
                [0] =＆GT;阿贾伊帕特尔
                [1] =＆GT;标签1
                [2] =＆GT;标签3
            ）
 

标签1被删除，因为它的2倍...

解决方案

  $结果2 = array_unique（call_user_func_array（'array_merge'，$结果2））;
 

all I want to remove the duplicate value from this Array

Array
(
    [0] => Array
        (
            [0] => Ajay Patel
            [1] => Tag 1
        )

    [1] => Array
        (
            [0] => Tag 1
            [1] => Tag 3
        )

    [2] => Array
        (
        )

    [3] => Array
        (
        )

    [4] => Array
        (
        )

)

I tried this solution from How to remove duplicate values from a multi-dimensional array in PHP

$result2 = array_map("unserialize", array_unique(array_map("serialize", $result2)));

But i think something is wrong here, i am getting this as result.

Array
(
    [0] => Array
        (
            [0] => Ajay Patel
            [1] => Tag 1
        )

    [1] => Array
        (
            [0] => Tag 1
            [1] => Tag 3
        )

    [2] => Array
        (
        )

)

What i want is

Array
            (
                [0] => Ajay Patel
                [1] => Tag 1
                [2] => Tag 3
            )

Tag 1 is removed because its 2 times...

解决方案

$result2 = array_unique(call_user_func_array('array_merge',$result2));
