PHP Code _php Tutorial for generating two-dimensional code

Two-dimensional code is a two-dimensional barcode, can be the URL, text, photos and other information through the corresponding encoding algorithm compiled into a block-shaped barcode pattern, mobile phone users can use the camera and decryption software to re-decode the relevant information and view the content

PHP class library PHP QR Code

# Two words to explain:
# contains qrlib.php words need to be put together with other files: files, folders.
# phpqrcode.php is a merged version that only needs to contain this file, but the resulting picture is slow and less accurate
# Here are two ways to use:

The code is as follows

Copy Code

Include ('./phpqrcode/phpqrcode.php '); Two-dimensional code data $data = ' http://gz.altmi.com '; The generated file name $filename = $errorCorrectionLevel. ' | '. $matrixPointSize. " 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 file QRCode::p ng (' Code data text ', ' filename.png '); Creates file # Generate image to browser QRCode::p ng (' some othertext 1234 '); Creates code image and outputs it directly into browser

If you create a color, you need to do it yourself.

Modify the code in the Color Settings section of the Qrimage class in Phpqrcode.php, 1.1.4 version of the Code on the No. 987, 988 lines, a foreground color, a background color:

The code is as follows	Copy Code
$col [0] = imagecolorallocate ($base _image,255,255,255); $col [1] = Imagecolorallocate ($base _image,0,0,0);

Can

Build with Google Open API

The code is as follows	Copy Code
$urlToEncode = "http://gz.altmi.com"; Generateqrfromgoogle ($urlToEncode); function Generateqrfromgoogle ($chl, $widhtHeight = ' Max ', $EC _level= ' L ', $margin = ' 0 ') { $url = UrlEncode ($url); Echo '; }
