header("Content-Type: image/png");
//二维码图片保存路径(若不生成文件则设置为false)
//$filename =ROOT_PATH . "public/uploads/bg/qrcode_" . time() . ".png";
$imgname = substr($imgname,0,-4);
$filename =ROOT_PATH . "public/uploads/bg/qrcode_" . $imgname . ".png";
//二维码容错率，默认L
$level = "L";
//二维码图片每个黑点的像素，默认4
$size = 4;
//二维码边框的间距，默认2
$padding = 2;
//保存二维码图片并显示出来，$filename必须传递文件路径
$saveandprint = true;
//生成二维码图片
@\PHPQRCode\QRcode::png($text,$filename,$level,$size,$padding,$saveandprint);
//ob_clean();
ob_end_clean();ob_clean();替换为 ob_end_clean(); 即可 最佳答案
