如何在 PHP 中合并两个对象数组 [英] How to merge two arrays of object in PHP

问题描述

我有以下两个对象数组:

I have the following two arrays of objects:

第一个数组: $array1

Array
(
    [0] => stdClass Object
        (
            [id] => 100
            [name] => Muhammad
        )

    [1] => stdClass Object
        (
            [id] => 102
            [name] => Ibrahim
        )

    [2] => stdClass Object
        (
            [id] => 101
            [name] => Sumayyah
        )
)

第二个数组: $array2

Array
(
    [0] => stdClass Object
        (
            [id] => 100
            [name] => Muhammad
        )

    [1] => stdClass Object
        (
            [id] => 103
            [name] => Yusuf
        )
)

我想合并这两个对象数组(去除所有重复项)并根据id排序.

I want to merge these two object arrays (removing all duplicates) and sorted according to id.

期望的输出:

Array
(
    [0] => stdClass Object
        (
            [id] => 100
            [name] => Muhammad
        )

    [1] => stdClass Object
        (
            [id] => 101
            [name] => Sumayyah
        )

    [2] => stdClass Object
        (
            [id] => 102
            [name] => Ibrahim
        )

    [3] => stdClass Object
        (
            [id] => 103
            [name] => Yusuf
        )
)

推荐答案

这 3 个简单的步骤完成了工作:

These 3 simple steps did the work:

//both arrays will be merged including duplicates
$result = array_merge( $array1, $array2 );
//duplicate objects will be removed
$result = array_map("unserialize", array_unique(array_map("serialize", $result)));
//array is sorted on the bases of id
sort( $result );
