laravel get items from two separate table and merge the result with pagination - laravel

Question

I have two tables, one of them is "posts" and the other one is "notifications". I want to show the users a list of posts and notifications with pagination. how can I do that efficiently?
I have this code that works fine but it is not efficient because I get all the data and then slice them. I want to do the pagination, using MYSQL
public function list_post_notification(Request $request , $page_number = 1 , $per_page=10 , $brand_id = null ){
$brand =$this->brandRepository->getMagazinBrand() ;
$posts = $brand->posts()->orderBy('posts.created_at' , 'desc')->take($page_number * $per_page) ;
$notifs = $brand->notifications()->orderBy('notifications.created_at' , 'desc')->take($page_number * $per_page) ;
$result = [] ;
foreach ($posts->get() as $k=>$v){
$item = [
'type'=>'post' ,
'uuid'=>$v->uuid,
'title'=>$v->title,
'created_at'=>strtotime($v->created_at),
'creator'=>$v->brand->fa_name,
'brand_id'=>$v->brand->id,
];
$result[$item['created_at']] =$item ;
}
foreach ($notifs->get() as $k=>$v){
$item = [
'type'=>'notification' ,
'uuid'=>$v->uuid,
'title'=>$v->title,
'created_at'=>strtotime($v->created_at),
'creator'=>$v->brand->fa_name,
'brand_id'=>$v->brand->id,
];
$result[$item['created_at']] =$item ;
}
krsort($result) ;
$start = 0 ;
if ($page_number > 1)
$start = ($page_number -1 ) * $per_page ;
return response()
->json(array_slice($result , $start , $per_page)) ;
}

You can merge all your items and create one Collection.
$resultCollection = collect($result).
Than use forPage method.
