How to save QR code with image to file

[sks1024]

I want to use the example of creating a QR code with image https://github.com/chillerlan/php-qrcode/blob/main/examples/imageWithLogo.php but I want to save it to file instead out outputting on screen. How can I do this? I am stumped. It works fine with outputting on screen.

I've tried this code but I can't get it to write. Would you mind sharing some code to get this to work?

Saving to file is implemented in the example you linked, make sure you're using the proper example for the php-qrcode version you have installed.

php 8.5.6 I know it can be done but I am beating my head trying to get it to work. Any help would be appreciated.

$qrcode->render($data, '/path/to/qrcode.svg'); as it is written in the documentation.

Thanks. That is what is getting me. There is no $data variable in this example I provided.

`$options->outputBase64 = false;
$options->cachefile = '/chillerlan/file.png';

$qrcode = new QRCode($options);
$qrcode->addByteSegment('https://github.com');

$qrOutputInterface = new QRImageWithLogo($options, $qrcode->getQRMatrix());

// dump the output, with an additional logo
// the logo could also be supplied via the options, see the svgWithLogo example
$out = $qrOutputInterface->dump(null, DIR.'/test1.png');`

//write to file here is what I need

I noticed the $options->cachefile parameter is not implemented in that particular example, the method parameter however is. It is the first parameter when you call the dump() method directly from the output instance:

// first param: output file path, second: logo file
 $qrOutputInterface->dump('/chillerlan/file.png', DIR.'/test1.png');

I guess I'll just move the handling of the cachefile setting to the saveToFile() method, or deprecate it entirely in favor of the method parameter...

that worked. thanks again for the quick response.

Happy to help!

One more quick one. How can I add a variable in the path od the addByteSegment function?

$qrcode->addByteSegment('https://danville.qr/track.php?'.$randstring.);

the URL in the QR code is getting $randstring insteadof the string I geenrated. Generator is workjing correctly.
