使用PHP QR Code类库创建中间带LOGO的二维码
使用PHPQRCode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"QRcodegenerated"."<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');
?>
