php-tcpdfHow can I generate a QR code using PHP and TCPDF?

Using PHP and TCPDF, you can generate a QR code by following these steps:

1. Include the TCPDF library in your PHP file:

require_once('tcpdf/tcpdf.php');

2. Create a new instance of the TCPDF class:

$pdf = new TCPDF();

3. Generate the QR code using the QRcode method:

$pdf->write2DBarcode('This is a QR code', 'QRCODE,H', 10, 10, 20, 20, $style, 'N');

4. Output the PDF file using the Output method:

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

The parts of the code are as follows:

• require_once('tcpdf/tcpdf.php');: This includes the TCPDF library in the PHP file.

• $pdf = new TCPDF();: This creates a new instance of the TCPDF class.

• $pdf->write2DBarcode('This is a QR code', 'QRCODE,H', 10, 10, 20, 20, $style, 'N');: This generates the QR code using the QRcode method, where 'This is a QR code' is the text to be encoded, 'QRCODE,H' is the type of barcode, 10, 10 is the x and y position of the barcode, 20, 20 is the width and height of the barcode, and 'N' is the mode of the barcode.

• $pdf->Output('example.pdf', 'I');: This outputs the PDF file using the Output method, where 'example.pdf' is the name of the file and 'I' is the output mode (I for inline, D for download).
