{
$url = urlencode($url);
echo ' QR code

widhtHeight="'.$size.'" widhtHeight="'.$size.'"/>';
}

Copy code

$urlToEncode="http://gz.altmi.com" ;

generateQRfromGoogle($urlToEncode);

function generateQRfromGoogle($chl,$widhtHeight ='150',$EC_level='L',$margin='0')

{

$url = urlencode($url);
echo ' QR code

代码如下	复制代码
include('./phpqrcode/phpqrcode.php'); // 二维码数据 $data = 'http://gz.altmi.com'; // 生成的文件名 $filename = $errorCorrectionLevel.'\|'.$matrixPointSize.'.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); ?>

widhtHeight="'.$size.'" widhtHeight="'.$size.'"/>';
