我有以下两个对象数组：

第一个数组： $array1

Array
(
    [0] => stdClass Object
        (
            [pid] => 1
            [pname] => iphone-6s
            [product_category] => 1
            [product_price] => 250
            [product_description] => Its iphone-6s, Apple Brand Products
            [product_image] => iPhone6s.png
            [uid] => 1
            [product_status] => Active
        )

    [1] => stdClass Object
        (
            [pid] => 2
            [pname] => Beauty Care
            [product_category] => 1
            [product_price] => 200
            [product_description] => Beauty Care's Products
            [product_image] => 2ca65f58e35d9ad45bf7f3ae5cfd08f1_beauty-care.png

        (
            [pid] => 4
            [pname] => Android tv
            [product_category] => 1,2
            [product_price] => 180
            [product_description] => Smart TV
            [product_image] => Android-TV.png

            [product_status] => Active
        )

)

第二个数组： $array2

Array
(
    [0] => stdClass Object
        (
            [mysummary] => Electronics

        (
            [mysummary] => Electronics
        )

    [3] => stdClass Object
        (
            [mysummary] => Sports, Books and Gaming etc.
        )

    [4] => stdClass Object
        (
            [mysummary] => Sports, Books and Gaming etc.
        )

    [5] => stdClass Object
        (
            [mysummary] => Electronics
        )

    [6] => stdClass Object
        (
            [mysummary] => Electronics
        )

    [7] => stdClass Object
        (
            [mysummary] => Electronics,Home & Furniture,Sports, Books and Gaming etc.,Beauty & Personal Care
        )

)

我想合并这两个对象数组

            [product_price] => 250
            [product_description] => Its iphone-6s, Apple Brand Products
            [product_image] => iPhone6s.png
            [uid] => 1
            [product_status] => Active
            [mysummary] => Electronics
        )

【问题讨论】：

我认为你可以使用array_merge()。 php.net/manual/en/function.array-merge.php
@Roshan 我试过了，但它没有给我我想要的输出。
你试过这个php.net/manual/en/function.array-merge-recursive.php
@RahulMeshram 是的，我试过了，它只进行合并，我正在寻找所需的输出。
@RahulMeshram 像这样合并数组：prnt.sc/mq8e36

标签： php arrays codeigniter multidimensional-array

【解决方案1】：

可以循环使用索引，将第二个数组的属性添加到第一个：

for ($index = 0; $index < count($array1); $index++) {
    $array1[$index]->mysummary = $array2[$index]->mysummary;
}

【讨论】：

它有效，但是，我在第二个对象中获得第一个 mysummary 值，在第三个对象中获得第二个值？？
@RïshïKêshKümar 正在使用相同的 $index。

【解决方案2】：

foreach ($array1 as $key => $value) {
    $array1[$key]->mysummary = $array2[$key]->mysummary;
}
echo '<pre>';print_r($array1);

【解决方案3】：

您可以使用array_map 和array_merge 的组合来实现相同的目的，而无需依赖数组的静态键。

$result = array_map(function($a,$b){  
    return array_merge(isset($a) ? $a : array(), isset($b) ? $b : array());
},$a1,$a2);

Demo.
