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.php.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:
<? include "phpqrcode/phpqrcode.php"; $value="http://www.php.com"; $errorCorrectionLevel = "L"; $matrixPointSize = "4"; QRcode::png($value, false, $errorCorrectionLevel, $matrixPointSize); exit; ?>
2,文件输出二维码
include('phpqrcode/phpqrcode.php');
// 二维码数据
$data = 'http://www.php.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);
3,生成中间带logo的二维码
<?php
include('phpqrcode/phpqrcode.php');
$value='http://www.php.com';
$errorCorrectionLevel = 'L';
$matrixPointSize = 6;
QRcode::png($value, 'xiangyang.png', $errorCorrectionLevel, $matrixPointSize, 2);
echo "QR code generated"."
";
$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');
?>
