删除重复值从PHP中的数组中完全删除 [英] Remove duplicated values completely deleted from array in php

问题描述

我想从数组中删除相同的值. 例如: 这是数组.

I want to remove the values from array which are same. For example: This is the array.

Array ( [0] => 1 [1] => 63 [2] => 1 )

核心php中是否有任何函数或某些东西，它们只能返回不重复的值，即具有索引号1的值并删除索引0和2 ，我想要结果

is there any function or something in core php which return me only the value which is not duplicate i.e value with index number 1 and delete index 0 and 2, I want the result

Array ( [1] => 63) 

有什么办法吗?

推荐答案

您可以使用 array_count_values()检查计数是否大于1.

You can use array_filter() and array_count_values() to check the count is not greater then 1.

<?php
$data = [1, 63, 1];

$data = array_filter($data, function ($value) use ($data) {
    return !(array_count_values($data)[$value] > 1);
});

print_r($data);

结果:

Array
(
    [1] => 63
)

也可以与多个重复项一起使用: https://3v4l.org/eJSTY

Will also work fine with multiple dupes: https://3v4l.org/eJSTY
