@AzizanNur you can get the imagepng($QR) result, base64 it then use as raw content on img src.

thanks for sharing this. worked without any issue

Thanks for that lovely snippet! 🙏🏻

I wonder if there's a way to output a SVG-file?
Has anyone an idea? 🤔

@nichtsooft The GD extension doesn't have built-in SVG export support, but there are probably external libraries that support this.

Though, since this code uses chart.googleapis.com to get QR images, converting to an SVG won't really give you what you expect.

I'd suggest finding an API/library that can generate QR code SVGs directly.

Thank you for the clarification!!! 👍🏻
