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://bbs.it-home.org";
- $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://bbs.it-home.org';
- // 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
-
-
include('phpqrcode/phpqrcode.php'); - $value='http://bbs.it-home.org';
- $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');
- ?>
