QRcode::png($value, false, $errorCorrectionLevel, $matrixPointSize); 
exit; 
?>

File output QR code

include('phpqrcode/phpqrcode.php');
// QR code data
$data = 'http://s.bookphone.cn';
// Generated file name
$filename = '1111.png';
// Error correction level: L, M, Q, H
$errorCorrectionLevel = 'L';
//Point size: 1 to 10
$matrixPointSize = 4;
QRcode::png($data, $filename, $errorCorrectionLevel, $matrixPointSize, 2);

Generate a two-dimensional pixel with logo in the middle Code

<?php 
include(&#39;phpqrcode/phpqrcode.php&#39;); 
$value=&#39;http://xy.bookphone.cn&#39;; 
$errorCorrectionLevel = &#39;L&#39;;

$QR = &#39;xiangyang.png&#39;; 
if($logo !== FALSE) 
{ 
$QR = imagecreatefromstring(file_get_contents($QR)); 
$logo = imagecreatefromstring(file_get_contents($logo)); 
$QR_width = imagesx($QR); 
$QR_height = imagesy($QR); 
$logo_width = imagesx($logo); 
$logo_height = imagesy($logo); 
$logo_qr_width = $QR_width / 5; 
$scale = $logo_width / $logo_qr_width; 
$logo_qr_height = $logo_height / $scale; 
$from_width = ($QR_width - $logo_qr_width) / 2; 
imagecopyresampled($QR, $logo, $from_width, $from_width, 0, 0, $logo_qr_width, $logo_qr_height, $logo_width, $logo_height);
