Answer 1

I found a solution to this today.
Assuming your fpdf.php file is in the directory app\ThirdParty
1- make the first line of the file fpdf.php look like this
<?php namespace App\ThirdParty;
2- In your controller add the line
use App\ThirdParty\FPDF;
3- Now you can create your pdf file
$pdf = new FPDF();
$pdf->AliasNbPages();
$pdf->SetAutoPageBreak(1,13);
$pdf->AddPage('P','A4');
$this->response->setHeader('Content-Type', 'application/pdf');
$pdf->Output('test.pdf','F');
The file will be stored in the public directory of ci4.
I hope I've helped you.

I resolved this by using the old way (i.e adding fpdf directly in app/Controllers/);
Firstly, make sure you have the latest version of fpdf installed. Mine is 1.82 then unzip in app/Controllers.
require('fpdf.php');//to be done in your controller
$pdf = new \FPDF();
$pdf->AliasNbPages();
$pdf->SetAutoPageBreak(1,13);
$pdf->AddPage('P','A4');
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$this->response->setHeader('Content-Type', 'application/pdf');
$pdf->Output('test.pdf','F');
In case you are using XAMPP for linux kindly update fpdf in /opt/lampp/lib/php.

First include font folder, fpdf.php file and fpdf.css file in the ThirdParty folder.
Open fpdf.php file and include following 2 lines after <?php
namespace App\ThirdParty;
use Exception;
Then rename the fpdf.php file in ThirdParty folder to FPDF.php
Now you can import fpdf using:
use App\ThirdParty\FPDF;
