PHP generates code for QR codes

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:

<?php    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 ';     The size of the point: 1 to    $matrixPointSize = 4;     QRCode::p ng ($data, $filename, $errorCorrectionLevel, $matrixPointSize, 2);? >  # Create a QR code file QRCode::p ng (' Code data text ', ' filename.png ');//creates file   # generate picture to browser QRCode::p ng (' some OT Hertext 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:

$col [0] = imagecolorallocate ($base _image,255,255,255); $col [1] = Imagecolorallocate ($base _image,0,0,0);

Can
Build with Google Open API

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