使用PHP QR Code類別庫建立中間帶LOGO的二維碼

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);
