Can't generate QR in PNG format

[taiwanleaftea]

I'm trying to generate QR code in PNG format, as is described in documentation:

$options = new QROptions();
$options->version = 7;
$options->outputInteface = QRGdImagePNG::class;
$options->outputBase64 = true; 
$render = new QRCodeRender($options);
$qr = $render->render('some URI');

I'm expecting to get something like data:image/png;base64,PD94bWwgdmVyc2l..., but instead the output is data:image/svg+xml;base64,PD94bWwgdmVyc2l...

What I do wrong?

The documentation you were using is probably the one for the dev-main branch, which is incompatible with v5 due to several deprecations (see #223).
This is the one you're looking for: https://php-qrcode.readthedocs.io/en/v5.0.x/Built-In-Output/QRGdImage.html

You have a typo: outputInteface should be outputInterface (with an 'r'). The QROptions class uses magic __set() which silently ignores misspelled properties, keeping the default QRMarkupSVG::class.

// Wrong:
$options->outputInteface = QRGdImagePNG::class;

// Correct:
$options->outputInterface = QRGdImagePNG::class;

Where is the typo? I see it in your first post, but it's not anywhere in this repo. Either way, the typo is not the only issue in case you are using v5.x

Oh sorry, I noticed just now that you are not the OP!

Correct, there is a tipo in my code outputInteface instead of outputInterface. Will try corrected version tomorrow.
I have version 5.0.5 installed. When I tried to switch documentation to version 5 instead of main and follow it, I got "depreciated" warnings from Phpstorm.

That is correct, the option is deprecated without replacement - it will work in v5 but is removed in v6. If that bothers you, you can use the manual invocation of the output instance as described in #223.

Switched to dev-main, corrected the typo. Everything Ok. Thank you.
