Use the PHP QR code library to create a two-dimensional code with logo in the middle
Using the PHP QR code class library to create a QR code

Using an example browser output:

Include "phpqrcode/phpqrcode.php";
$value = "Http://s.bookphone.cn/chinabook/index.php/adminhtml/Croles/admin";
$errorCorrectionLevel = "L";
$matrixPointSize = "4";
QRCode::p ng ($value, False, $errorCorrectionLevel, $matrixPointSize);
Exit
?>

File output two-dimensional code

Include (' phpqrcode/phpqrcode.php ');
Two-dimensional code data
$data = ' http://s.bookphone.cn ';
The generated file name
$filename = ' 1111.png ';
Error correction level: L, M, Q, H
$errorCorrectionLevel = ' L ';
Size of point: 1 to 10
$matrixPointSize = 4;
QRCode::p ng ($data, $filename, $errorCorrectionLevel, $matrixPointSize, 2);

Create a two-dimensional code with logo in the middle

Include (' phpqrcode/phpqrcode.php ');
$value = ' http://xy.bookphone.cn ';
$errorCorrectionLevel = ' L ';
$matrixPointSize = 6;
QRCode::p ng ($value, ' xiangyang.png ', $errorCorrectionLevel, $matrixPointSize, 2);
echo "QR code generated". "
";
$logo = ' logo.png ';
$QR = ' xiangyang.png ';

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, $logo _ height);
}
Imagepng ($QR, ' xiangyanglog.png ');
?>
