Are there alternative methods or tools, aside from fpdf, for converting documents to PDF using PHP?

To convert documents to PDF using PHP without using fpdf, you can utilize other libraries such as TCPDF, mPDF, or Dompdf. These libraries provide similar functionality for generating PDF files from various sources like HTML, images, or text.

// Example using TCPDF library
require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF();
$pdf->AddPage();
$pdf->SetFont('Arial', '', 12);
$pdf->Write(0, 'Hello World');
$pdf->Output('example.pdf', 'D');
