使用PHP QR Code类库创建二维码使用举例浏览器输出：<?include "phpqrcode/phpqrcode.php";$value="http://s.bookphone.cn/chinabook/index.php/adminhtml/Croles/admin";$errorCorrectionLevel = "L";$matrixPointSize = "4";QRcode::png($value,false,$errorCorrectionLevel,$matrixPointSize);exit;?>文件输出二维码include('phpqrcode/phpqrcode.php');// 二维码数据$data = 'http://s.bookphone.cn';// 生成的文件名$filename = '1111.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);生成中间带logo的二维码<?phpinclude('phpqrcode/phpqrcode.php');$value='http://xy.bookphone.cn';$errorCorrectionLevel = 'L';$matrixPointSize = 6;QRcode::png($value, 'xiangyang.png', $errorCorrectionLevel,$matrixPointSize, 2);echo "QR code generated"."<br />";$logo = 'logo.png';$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');?>
使用PHP QR Code类库创建二维码

使用举例浏览器输出：

<?
include "phpqrcode/phpqrcode.php";
$value="http://s.bookphone.cn/chinabook/index.php/adminhtml/Croles/admin";
$errorCorrectionLevel = "L";
$matrixPointSize = "4";
QRcode::png($value, false, $errorCorrectionLevel, $matrixPointSize);
exit;
?>

文件输出二维码

include('phpqrcode/phpqrcode.php');
// 二维码数据
$data = 'http://s.bookphone.cn';
// 生成的文件名
$filename = '1111.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);

生成中间带logo的二维码

<?php
include('phpqrcode/phpqrcode.php');
$value='http://xy.bookphone.cn';
$errorCorrectionLevel = 'L';
$matrixPointSize = 6;
QRcode::png($value, 'xiangyang.png', $errorCorrectionLevel, $matrixPointSize, 2);
echo "QR code generated"."<br />";
$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');
?>
