二维码在线生成图片PHP源代码
二维码现在变得越来越流行了,这里介绍两端PHP的二维码生成代码,一段使用了Google开放的二维码API,另一段使用的是PHP QR Code二维码开源类库,都很简单。
1、使用Google Chart API生成二维码图片
Google Chart API是一个功能十分强大的API,生成二维码仅仅是其中的一个小功能。这里只介绍二维码部分,如果想了解更多功能,可以登录官网地址:http://code.google.com/intl/zh-CN/apis/chart/
代码如下:
$urlToEncode="http://www.weste.net";
generateQRfromGoogle($urlToEncode);
function generateQRfromGoogle($chl,$widhtHeight ='150',$EC_level='L',$margin='0')
{
$url = urlencode($url);
echo '';
}
?>

2、使用PHP QR Code生成二维码图片
PHP QR Code是一个开源的php二维码开源类库,基于libqrencode C库,并提供API代码创建QR条码图像,支持png、jpg格式。功能强大,使用起来也非常简单。
demo代码如下:
include "./phpqrcode/phpqrcode.php";
$value="http://www.weste.net";
$errorCorrectionLevel = "L";
$matrixPointSize = "4";
QRcode::png($value, false, $errorCorrectionLevel, $matrixPointSize);
exit;
?>
