To generate a QR code in PHP, you can use a third-party library such as PHP QR Code. Here is an example of how to use it:

  1. Download the PHP QR Code library from https://sourceforge.net/projects/phpqrcode/
  2. Extract the downloaded zip file and include the PHP QR Code library in your PHP script:
1
include "phpqrcode/qrlib.php";


  1. Use the QRcode::png function to generate a QR code image and save it to a file or output it to the browser:
1
2
3
4
$text = "This is the text that will be encoded in the QR code";
$file = "qrcode.png"; // or you can use $file = NULL; to output the image directly to the browser

QRcode::png($text, $file);


You can also specify additional options such as the size and error correction level of the QR code by passing them as an array to the second argument of the QRcode::png function. For example:

1
2
3
4
5
6
$options = array(
    'size' => 5,
    'level' => 'H'
);

QRcode::png($text, $file, $options);


For more information, you can refer to the PHP QR Code library documentation at https://phpqrcode.sourceforge.io/.
