PHP Extension Doesn't Seem Working

[Fliw]

What happened?

Hi, when i using firebase i got error like this when using FrankenPHP Firebase messaging error {"error_type":"GuzzleHttp\\Exception\\ConnectException","error_message":"HTTP/2 is supported by the cURL handler, however libcurl is built without HTTP/2 support.","error_code":0

but when i use FPM it work normally, i've checked the extension that running in frankenPHP and it says Curl is already enabled. i use franken from octane laravel.

This is output of the static frankenphp binary you get with curl https://frankenphp.dev/install.sh | sh

You selected Build Type: Custom (tell us more in the description), but didn't tell us anything, so I don't know where the issue would be. Also please add a minimal piece of php code to reproduce this, as I suspect the error message may be incorrect.

[henderkes]

<?php

$ch = curl_init('https://www.google.com/');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_2_0);
curl_exec($ch);

if (curl_errno($ch)) {
    die('CURL error: ' . curl_error($ch));
}

$protocol = curl_getinfo($ch, CURLINFO_HTTP_VERSION);
if ($protocol !== 3) { // CURLINFO_HTTP_VERSION returns 3 for HTTP/2
    die('HTTP/2 not used');
}

echo "HTTP/2 supported and used.\n";
curl_close($ch);

Works in both docker and the static binary (which your phpinfo output indicates).

the curl info is :

i use octane laravel with server frankenphp, and use nginx as proxy forwarder, here is my nginx config for octane listening

then i use --https when run octane, so nginx hit https, it return only blank with no response from nginx

[henderkes]

This issue might have to be raised with the maintainers of Octane then, FrankenPHP builds with H2 and H3 support.

And I'm not sure why you're using nginx at all when FrankenPHP can directly serve https.

[Fliw]

Okayy thankyou, the docs of laravel says when use for production it must be served over traditional webserver such as nginx, i will add this issue to them.

[henderkes]

They're saying that you should not be using octane (the command to spin up the server) in production at all. You should directly use nginx + fpm or frankenphp, either as a docker image, the (gnu) static binary or the (soon to be released) system packages, currently available for testing here: https://rpms.henderkes.com/

They do not mean that you should be using nginx as a reverse proxy behind octane. That would result in the worst of both worlds.
