如何从PHP中的多维数组删除重复值？

例如数组：

 阵列
（
    [0] =＆GT;排列
（
[0] =＆GT; ABC
[1] =＆GT; DEF
）    [1] =＆GT;排列
（
[0] =＆GT; GHI
[1] =＆GT; JKL
）    [2] =＆GT;排列
（
[0] =＆GT; MNO
[1] =＆GT; PQL
）    [3] =＆GT;排列
（
[0] =＆GT; ABC
[1] =＆GT; DEF
）    [4] =＆GT;排列
（
[0] =＆GT; GHI
[1] =＆GT; JKL
）    [5] =＆GT;排列
（
[0] =＆GT; MNO
[1] =＆GT; PQL
））
 

解决方案

下面是另一种方式。没有中间变量保存。

我们用它来删除重复的结果，从各种重叠的查询。

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

How can I remove duplicate values from a multi-dimensional array in PHP?

Example array:

Array
(
    [0] => Array
	(
	    [0] => abc
	    [1] => def
	)

    [1] => Array
	(
	    [0] => ghi
	    [1] => jkl
	)

    [2] => Array
	(
	    [0] => mno
	    [1] => pql
	)

    [3] => Array
	(
	    [0] => abc
	    [1] => def
	)

    [4] => Array
	(
	    [0] => ghi
	    [1] => jkl
	)

    [5] => Array
	(
	    [0] => mno
	    [1] => pql
	)

)

解决方案

Here is another way. No intermediate variables are saved.

We used this to de-duplicate results from a variety of overlapping queries.

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