Are there any best practices for handling barcode generation and output in PHP using TCPDF?

When generating barcodes in PHP using TCPDF, it is recommended to use the TCPDFBarcode class provided by TCPDF. This class allows for easy generation of various types of barcodes such as Code 128, QR Code, and Data Matrix. To output the barcode in the PDF document, you can use the TCPDF methods to set the barcode parameters and then add it to the PDF.

// Include the TCPDF library
require_once('tcpdf/tcpdf.php');

// Create new TCPDF object
$pdf = new TCPDF();

// Add a new page
$pdf->AddPage();

// Set barcode parameters
$barcodeValue = '123456789';
$barcodeType = 'C128';
$barcodeDisplay = 'C';
$barcodeSize = 50;
$barcodePosX = 50;
$barcodePosY = 50;

// Add barcode to the PDF
$pdf->write1DBarcode($barcodeValue, $barcodeType, $barcodePosX, $barcodePosY, '', $barcodeSize, 0.4, $barcodeDisplay);

// Output the PDF
$pdf->Output('output.pdf', 'I');
