使用PHP QR Code类库创建二维码
使用举例浏览器输出:
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'); ?>
