What are some popular libraries or tools for implementing barcodes or QR codes in FPDF for PDF forms?

To implement barcodes or QR codes in FPDF for PDF forms, you can use libraries such as TCPDF or FPDI. These libraries provide functions to easily generate barcodes and QR codes within your PDF forms. By integrating these libraries into your FPDF project, you can enhance the functionality of your PDF forms by including dynamic barcode or QR code generation. 

// Example using TCPDF to generate a QR code in FPDF
require('tcpdf/tcpdf.php');

$pdf = new TCPDF();
$pdf->AddPage();

// Set QR code content
$qr_content = 'https://www.example.com';
$qr_code = QRcode::png($qr_content, 'qrcode.png', QR_ECLEVEL_L, 3);

// Insert QR code into PDF
$pdf->Image('qrcode.png', 10, 10, 50, 50, 'PNG');

$pdf->Output('example.pdf', 'I');
