Yii2 merge arrays - php

Question

I need merge arrays for json API. I have 3 requests:
$data['winners'] = Winners::find()->limit(8)->all();
$user = User::findIdentity($value->user_id);
$product = Products::find()->localized($lang)->where(['coupon' => $value->coupon])->one();
I need foreach all $data['winners'], get User with id from $data['winners'], and get Product from $data['winners']. After i need merge in 1 json all my data.
I try like this:
$data['winners'] = Winners::find()->limit(8)->all();
foreach ($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

There is an even more elegant solution in PHP:
$winners = Winners::find()->limit(8)->all();
foreach ($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;
The PHP array operator [] in $data[] adds an array element at the end of the $data array.

If i understand correctly you question you need an array with all the $data[winners] istances and foreach instance merge the related Produce and User
then you could use
$result[] = array_merge($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);
}

I found solution:
$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;
