php - How can I paginate a merged collection in Laravel 5?

Question

I am creating a stream which contains two types of objects, BluePerson and RedPerson. To create the stream, I fetch all of both objects, then merge them into one collection. After doing so, I need to paginate them, however paginate is for eloquent models and DB queries, and not collections, it seems. I have seen a lot about manually creating a paginator, but the documentation, especially in the API is sparse (I can't even seem to find the arguments the Paginator class accepts.)

How can I paginate the results of merging my collections?

public function index()
{
    $bluePerson = BluePerson::all();
    $redPerson = RedPerson::all();

    $people = $bluePerson->merge($redPerson)->sortByDesc('created_at');


    return view('stream.index')->with('people', $people);
}

You are right. but there is ineed a paginator function for collections. forPage

Syntax:

Collection forPage(int $page, int $perPage)

Example:

Rest is simple.

public function foo()
{
    $collection = collect([1,2,3,4,5,6,7,8,9,0]);
    $items = $collection->forPage($_GET['page'], 5); //Filter the page var
    dd($items);
}
