Yii2 合并数组

Question

我需要 json API 的合并数组。我有 3 个请求：

$data['winners'] = Winners::find()->limit(8)->all();

$user = User::findIdentity($value->user_id);

$product = Products::find()->localized($lang)->where(['coupon' => $value->coupon])->one();

我需要获取所有 $data['winners']，从 $data['winners'] 中获取具有 ID 的用户，并从 $data['winners'] 中获取产品。在我需要合并 1 json 我所有的数据之后。

我这样试：

$data['winners'] = Winners::find()->limit(8)->all();
        foreach ($data['winners'] as $value){
            $user = User::findIdentity($value->user_id);
            $product = Products::find()->localized($lang)->where(['coupon' => $value->coupon])->one();
            $result = ArrayHelper::merge($product, $user);
        }

Answer 1

如果我理解正确，你质疑你需要一个包含所有 $data[winners] 实例的数组，并且 foreach 实例合并相关的 Produce 和 User 那么你可以使用

 $result[] = array_merge($value, $product, $user);

.

    $data['winners'] = Winners::find()->limit(8)->all();
    foreach ($data['winners'] as $value){
        $user = User::findIdentity($value->user_id);
        $product = Products::find()->localized($lang)->where(['coupon' => $value->coupon])->one();
        $result[] = array_merge($value, $product, $user);
    }

Answer 2

我找到了解决方案：

$winners = Winners::find()->limit(8)->all();
        $i = 0;
        foreach ($winners as $value){
            $user = User::findIdentity($value->user_id);
            $product = Products::find()->localized($lang)->where(['coupon' => $value->coupon])->one();
            $data[$i]['image'] = $product->prize_image;
            $data[$i]['user'] = $user->firstname.' '.$user->lastname;
            $data[$i]['title'] = $product->win_title;
            $i++;
        }
        return $data;

Answer 3

PHP中有一个更优雅的解决方案：

    $winners = Winners::find()->limit(8)->all();
    foreach ($winners as $value){
        $user = User::findIdentity($value->user_id);
        $product = Products::find()->localized($lang)
            ->where(['coupon' => $value->coupon])->one();
        $data[] = [
            'image'=> $product->prize_image,
            'user' => $user->firstname.' '.$user->lastname,
            'title' => $product->win_title,
        ];
    }
    return $data;

$data[]中的PHP array operator[]在$data数组的末尾添加了一个数组元素。
