What are the potential risks or complications of using PHP to manipulate PDF files?

One potential risk of using PHP to manipulate PDF files is the possibility of introducing security vulnerabilities if the code is not properly sanitized. To mitigate this risk, it is important to validate user input and use secure libraries or functions for handling PDF files. 

// Example of using the TCPDF library to manipulate PDF files securely
require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF();
$pdf->AddPage();
$pdf->SetFont('Helvetica', '', 12);
$pdf->Cell(0, 10, 'Hello, World!', 0, 1, 'C');
$pdf->Output('example.pdf', 'F');
