In this article, we will learn how we can convert an array to collection with pagination. To achieve this, we will build a simple function to convert an array to a collection.
Let’s first add a route for displaying our records with pagination. Simply, add the below code in your web.php routes file.
//web.php
Route::get('array-to-collection', 'DemoController@index');
Now, we will create a new controller DemoController with index method inside it so that when we hit the route array-to-collection, this method will be hit. Let’s write some code into our controller and describe the process later.
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Pagination\Paginator;
use Illuminate\Support\Collection;
use Illuminate\Pagination\LengthAwarePaginator;
class DemoController extends Controller
{
/**
* Convert array to collection method
*
* @var view
*/
public function index()
{
$array = [
['id'=>1, 'title'=>'Demo Article 1'],
['id'=>2, 'title'=>'Demo Article 2'],
['id'=>3, 'title'=>'Demo Article 3'],
['id'=>4, 'title'=>'Demo Article 4'],
['id'=>5, 'title'=>'Demo Article 5'],
['id'=>6, 'title'=>'Demo Article 6'],
['id'=>7, 'title'=>'Demo Article 7'],
['id'=>8, 'title'=>'Demo Article 8'],
['id'=>9, 'title'=>'Demo Article 9'],
['id'=>10, 'title'=>'Demo Article 10'],
];
$articles = $this->convertArrayToCollection($array);
dd($articles);
}
/**
* helper function to convert array to paginated collection
*
* @var collection
*/
public function convertArrayToCollection($items, $perPage = 5, $page = null, $options = [])
{
$page = $page ?: (Paginator::resolveCurrentPage() ?: 1);
$items = $items instanceof Collection ? $items : Collection::make($items);
return new LengthAwarePaginator($items->forPage($page, $perPage), $items->count(), $perPage, $page, $options);
}
}
In the above code, we are creating a simple array $array. Then, we are creating a convertArrayToCollection method which converts our array to the paginated collection. If we visit the route /array-to-collection route, we will see the collection with pagination instead of an array.
