use App\Http\Controllers\PDFController;
  
Route::get('merge-pdf', [PDFController::class, 'index']);
Route::post('merge-pdf', [PDFController::class, 'store'])->name('merge.pdf.post');

Step 4: Create Controller

Here,we require to create new controller PDFController that will manage get and post method of route. So let's put bellow code.

app/Http/Controllers/PDFController.php

<?php
      
namespace App\Http\Controllers;
       
use Illuminate\Http\Request;
use setasign\Fpdi\Fpdi;
    
class PDFController extends Controller
{
     
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        return view('mergePDF');
    }
        
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {   
        $this->validate($request, [
                'filenames' => 'required',
                'filenames.*' => 'mimes:pdf'
        ]);
      
         if($request->hasFile('filenames')){
            $pdf = new Fpdi();
      
            foreach ($request->file('filenames') as $key => $value) {
                
                $pageCount =  $pdf->setSourceFile($value->getPathName());
 
                for ($i=0; $i AddPage();

                    //import a page then get the id and will be used in the template
                    $tplId = $pdf->importPage($i+1);

                    //use the template of the imporated page
                    $pdf->useTemplate($tplId);
                }

            }

            return response($pdf->Output())
                    ->header('Content-Type', 'application/pdf');
  
        }
    }

            <div class="alert alert-danger">
                <ul>
                  @foreach ($errors->all() as $error)

                  @endforeach
                </ul>
            </div>
            @endif
                 
            <form method="post" action="{{ route('merge.pdf.post') }}" enctype="multipart/form-data">
                  {{csrf_field()}}
                  <input type="file" name="filenames[]" class="myfrm form-control" multiple="">
                  <button type="submit" class="btn btn-success" style="margin-top:10px">Submit</button>
