Как объединить два массива объектов одинакового размера в PHP

Question

У меня есть два следующих массива объектов:

Первый массив: $ array1

Array

            [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

            [uid] => 1
            [product_status] => Active
        )

Answer 1

Вы можете использовать комбинацию array_map и array_merge , чтобы добиться того же, не зависимо от статического ключа массивов.

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

Demo .

Answer 2

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

Answer 3

Вы можете циклически использовать индекс и добавить атрибут второго массива в первый:

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