php生成二维码的类库(QRCode方法)

2. include "phpqrcode/phpqrcode.php";
3. $value="http://bbs.it-home.org";
4. $errorCorrectionLevel = "L";
5. $matrixPointSize = "4";
6. QRcode::png($value, false, $errorCorrectionLevel, $matrixPointSize);
7. exit;
8. ?>

文件输出二维码：

2. include('phpqrcode/phpqrcode.php');
3. // 二维码数据
4. $data = 'http://s.bookphone.cn';
5. // 生成的文件名
6. $filename = '1111.png';
7. // 纠错级别：L、M、Q、H
8. $errorCorrectionLevel = 'L';
9. // 点的大小：1到10
10. $matrixPointSize = 4;
11. QRcode::png($data, $filename, $errorCorrectionLevel, $matrixPointSize, 2);
12. ?>

生成中间带logo的二维码：

3. //带中间logo的二维码

4. //by bbs.it-home.org
5. include('phpqrcode/phpqrcode.php');
6. $value='http://bbs.it-home.org';
7. $errorCorrectionLevel = 'L';
8. $matrixPointSize = 6;
9. QRcode::png($value, 'jbxue.png', $errorCorrectionLevel, $matrixPointSize, 2);
10. echo "QR code generated"."
    ";
11. $logo = 'logo.png';
12. $QR = 'jbxue.png';

13. if($logo !== FALSE)

14. {

15. $QR = imagecreatefromstring(file_get_contents($QR));

16. $logo = imagecreatefromstring(file_get_contents($logo));
17. $QR_width = imagesx($QR);
18. $QR_height = imagesy($QR);
19. $logo_width = imagesx($logo);
20. $logo_height = imagesy($logo);
21. $logo_qr_width = $QR_width / 5;
22. $scale = $logo_width / $logo_qr_width;
23. $logo_qr_height = $logo_height / $scale;
24. $from_width = ($QR_width - $logo_qr_width) / 2;
25. imagecopyresampled($QR, $logo, $from_width, $from_width, 0, 0, $logo_qr_width, $logo_qr_height, $logo_width, $logo_height);
26. }
27. imagepng($QR,'jbxue_log.png');
28. ?>
