我们要生成二维码都需要借助一些类库来实现了,下面我介绍利用PHP QR Code生成二维码吧,生成方法很简单,下面我来介绍一下.

利用php类库PHP QR Code来实现,不需要装额外的php扩展,首先下载类库包,有时候地址打不开,地址:http://phpqrcode.sourceforge.net/

下载:
国内下载:http://www.bitsCN.com/codes/189897.html
国外下载:http://sourceforge.net/projects/phpqrcode/

例子,使用PHP QR Code类库创建二维码。

1,浏览器输出:

<&#63; 
include "phpqrcode/phpqrcode.php"; 
$value="http://www.bitsCN.com"; 
$errorCorrectionLevel = "L"; 
$matrixPointSize = "4"; 
QRcode::png($value, false, $errorCorrectionLevel, $matrixPointSize); 
exit; 
&#63;>
Copy after login

2,文件输出二维码

include('phpqrcode/phpqrcode.php'); 
// 二维码数据 
$data = 'http://www.jbxue.com'; 
// 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);
Copy after login

3,生成中间带logo的二维码

<&#63;php 
include('phpqrcode/phpqrcode.php'); 
$value='http://www.bitsCN.com'; 
$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'); 
&#63;>
Copy after login
