PHP generates QR code example code

What is QR code? QR code is a type of two-dimensional barcode that can compile information such as website addresses, text, photos, etc. 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. # Two sentences 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:

 include('./phpqrcode/phpqrcode.php');
 // QR code data
 $data = 'http://bbs.it-home.org';
 // Generated file name
 $filename = $errorCorrectionLevel.'|'.$matrixPointSize.'.png';
 // Error correction level: L, M, Q, H
 $errorCorrectionLevel = 'L';
 // Point size: 1 to 10
 $matrixPointSize = 4;
 QRcode::png($data, $filename, $errorCorrectionLevel, $matrixPointSize, 2);
?>

# Create a QR code file
QRcode: :png('code data text', 'filename.png');
// creates file

# Generates images to the browser
QRcode::png('some othertext 1234');
// creates code image and outputs it directly into browser

If you need to generate colorful ones, you need to do it yourself Modify the color setting part of the code in the image method of the QRimage class in phpqrcode.php. The 1.1.4 version of the code is on lines 987 and 988, with one foreground color and one background color:

$col[0] = ImageColorAllocate($base_image,255,255,255);
$col[1] = ImageColorAllocate($base_image,0,0,0);
