What are some common methods for creating PDF documents from HTML/PHP content?

One common method for creating PDF documents from HTML/PHP content is to use a library like TCPDF or mpdf. These libraries allow you to generate PDF files from HTML content using PHP code. Another approach is to use the FPDF library, which provides a way to create PDF files directly from PHP without the need for HTML conversion.

// Using TCPDF library
require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF();
$pdf->AddPage();
$pdf->writeHTML('<h1>Hello World!</h1>');
$pdf->Output('example.pdf', 'D');

// Using FPDF library
require('fpdf/fpdf.php');

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