使用PHP QR Code類別庫建立二維碼
使用範例瀏覽器輸出：
<? 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; ?>
檔案輸出二維碼
include('phpqrcode/phpqrcode.php'); $data = 'http://s.bookphone.cn';
// 產生的檔案名稱
$filename = '1111.png';
// 錯誤等級：L、M、Q、H
$errorCorrectionLevel = 'L';
// 點的大小：1到10
$matrixPointSize = 4;
QRcode::png($data, $filename, $errorCorrectionLevel, $matrixPointSize, 2);
碼
<?php
include('phpqrcode/phpqrcode.php');
$value='http://xy.bookphone.cn';
$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');
?>
