如何进行特定的合并

Question

我正在尝试将两个数组合并到一个结果中

$array1 =["pack_id","pack_name","cash"];

$array2 =["pack_id","pack_name","inactifs","actifs","total"];

我的代码如下：

 for ($i = 0; $i < count($cashByPacks); $i++) {
            $result[$i] = array('pack_id' => $cashByPacks[$i]->pack_id, 'pack_name' => $cashByPacks[$i]->pack_name, 'effectif' => 0, 'cash' => $cashByPacks[$i]->cash ?? 0, 'actif' => 0, 'inactif' => 0, 'percent' => 0);

            for ($j = 0; $j < count($query); $j++) {
                if (array_search($query[$j]->pack_id, $result[$i])) {
                    $result[$j] = array('pack_id' => $query[$j]->pack_id, 'pack_name' => $query[$j]->pack_name, 'effectif' => $query[$j]->total, 'actif' => $query[$j]->actifs, 'inactif' => $query[$j]->inactifs, 'cash' => $cashByPacks[$i]->cash ?? 0, 'percent' => ($cashByPacks[$i]->cash == 0) ? 0 : round(($cashByPacks[$i]->cash / $totalcash) * 100, 2));
                }

            }
        }
        return $result;

我希望输出将是一个包含以下内容的数组：

["pack_id","pack_name","cash","actifs","inactifs","totale"]

使用 array_merge 和 array_diff。
Array_diff 查找两个数组之间的不同之处，array_merge 将两者合并。

$arr1 = ["pack_id","pack_name","cash"];

$arr2 =["pack_id","pack_name","inactifs","actifs","total"];

$res = array_merge($arr1, array_diff($arr2, $arr1));

var_dump($res);

或者使用 array_merge 和 array_unique。
Array_merge 将合并两个数组并创建重复项，array_unique 将删除重复项。

$arr1 = ["pack_id","pack_name","cash"];

$arr2 =["pack_id","pack_name","inactifs","actifs","total"];

$res = array_unique(array_merge($arr1, $arr2));

var_dump($res);
