我有一个带有精确值的二维码输出，但我不知道如何存储生成的图像。 如何存储二维码图像？

Question

In the code I have a value string as a test and I am getting an output once I scan qr-code. I would like to store that qr-code image in a folder.

include 'phpqrcode/qrlib.php';
$value = "test";
if($count > 0)
{                 
     QRcode::png('code data text', 'filename.png'); // creates file 
     $result = QRcode::png($values); // creates code image and outputs it 
                                                directly into browser
}

Answer 1

You have 3 options,

1. Just store the coded data text in a file or database
2. Store the qrcode binary in a database ( QRcode::text($codeContents) )
3. Store the qrcode to a file like @DarkBee said QRcode::png($codeContents, $pngAbsoluteFilePath);

Good luck!
