QR code is a type of two-dimensional barcode. It can compile website addresses, text, photos and other information into a square barcode pattern through corresponding encoding algorithms. Mobile phone users can re-decode the relevant information and view the content through the camera and decoding software

php class library PHP QR Code

# Two sentence explanation:
# If you include qrlib.php, you need to put it together with other files: files and folders.
# phpqrcode.php is the merged version, you only need to include this file, but the generated image is slow and inaccurate
# Two usages are given below:

The code is as follows

代码如下

复制代码

include('./phpqrcode/phpqrcode.php');
// 二维码数据
$data = 'http://gz.altmi.com';
// 生成的文件名
$filename = $errorCorrectionLevel.'|'.$matrixPointSize.'.png';
// 纠错级别：L、M、Q、H
$errorCorrectionLevel = 'L';
// 点的大小：1到10
$matrixPointSize = 4;
QRcode::png($data, $filename, $errorCorrectionLevel, $matrixPointSize, 2);

?>

# 创建一个二维码文件
QRcode::png('code data text', 'filename.png');
// creates file

# 生成图片到浏览器
QRcode::png('some othertext 1234');
// creates code image and outputs it directly into browser

Copy code

include('./phpqrcode/phpqrcode.php');

// QR code data

代码如下	复制代码
$col[0] = ImageColorAllocate($base_image,255,255,255); $col[1] = ImageColorAllocate($base_image,0,0,0);

$data = 'http://gz.altmi.com';

// Generated File name

$filename = $errorCorrectionLevel.'|'.$matrixPointSize.'.png';

// Error correction level: L, M, Q, H
$errorCorrectionLevel = 'L';

// Point size: 1 to 10

代码如下	复制代码
$urlToEncode="http://gz.altmi.com"; generateQRfromGoogle($urlToEncode); function generateQRfromGoogle($chl,$widhtHeight ='150',$EC_level='L',$margin='0') { $url = urlencode($url); echo ''; }

$matrixPointSize = 4; QRcode::png($data, $filename, $errorCorrectionLevel, $matrixPointSize, 2);?> ;
# Create a QR code file

QRcode::png('code data text', 'filename.png');

The code is as follows

Copy code

$col[0] = ImageColorAllocate($base_image,255,255,255);$col[1] = ImageColorAllocate($base_image,0,0,0); You canuse google open api to generate

The code is as follows

Copy code

$urlToEncode="http://gz.altmi.com"; generateQRfromGoogle($urlToEncode) ; function generateQRfromGoogle($chl,$widhtHeight ='150',$EC_level='L',$margin='0') { $url = urlencode($url); echo ' QR code
