获取重复的多维数组值 [英] Get duplicate multi-d array value

问题描述

我想从数组中获取所有重复值，但是我在这里看到的是如何删除它们，有什么办法可以只检索重复项并显示它们重复了多少次？

I would like to get all the duplicate values from an array, but all i see here is how to remove them, is there any way in retrieving only the duplicates and showing how many times they have duplicated?

例如

array(
  array(1,2,3,4,5,6),
  array(6,5,4,3,2,1),
  array(1,2,3,4,5,6),
  array(3,4,8,4,3,1),
  array(6,5,4,3,2,1),
)

我想像
数组（1,2,3,4,5,6）重复2次
和
array（6,5,4,3,2,1）也重复了2次

I want to have like array(1,2,3,4,5,6) duplicated 2 times and array(6,5,4,3,2,1) also duplicated 2 times

那些没有重复的将被忽略。

Those that are not duplicated will be ignored.

推荐答案

演示

foreach($array as $arr)
{
  $o[implode(',', $arr)][] = 1;
}
array_walk($o, function($v, $k){echo $k.':'.count($v);});
