What are the potential challenges when trying to combine the html2pdf and fpdf classes?

When trying to combine the html2pdf and fpdf classes, one potential challenge is that both classes may have conflicting methods or properties, leading to errors or unexpected behavior. To solve this, you can extend one of the classes and override any conflicting methods or properties to ensure compatibility.

<?php
require('html2pdf.php');
require('fpdf.php');

class MyPDF extends HTML2PDF {
    // Override any conflicting methods or properties here
}

$pdf = new MyPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
