Are there any alternative libraries or methods for handling PDF documents in PHP?

Handling PDF documents in PHP can be done using libraries like TCPDF, FPDF, or mPDF. These libraries provide functions to create, modify, and extract content from PDF files. Alternatively, you can use the PDFtk library to manipulate PDF files through command-line operations.

// Example using TCPDF library to create a PDF document
require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF();
$pdf->AddPage();
$pdf->SetFont('Arial', 'B', 16);
$pdf->Cell(0, 10, 'Hello World', 0, 1, 'C');
$pdf->Output('example.pdf', 'I');
