Invalid data for JSON encoding leads to blank page

[aleho]

Using json_encode without JSON_THROW_ON_ERROR masks invalid JSON data. This in turn leads to invalid JS being generated (opstate: ,) and a blank page. For me the data is invalid because of the error Inf and NaN cannot be JSON encoded.

Improving encoding with flags, e.g., json_encode($opcache->getData(), JSON_THROW_ON_ERROR | JSON_PARTIAL_OUTPUT_ON_ERROR), finally works.

A big problem here (FrankenPHP) seems to be that opcache_get_configuration() doesn't make a lot of sense, $config['directives'['opcache.memory_consumption'] seems to always report 0 for example.

Probably related: php/php-src#16927

Thanks for that @aleho. I've not tried it with FrankenPHP, but will look into it as soon as I can.

On a side note; how are you liking FrankenPHP? Are you using it for the potential speed increases and has it been working out for you?

All my setups in the last 6 years were Caddy + FPM (including automatic certificates), so replacing that with FrankenPHP was very easy. That migration was actually done for reducing complexity.

Migrating to worker mode is trickier though. I recently had memory leaks I still could not diagnose fully. Just a simple class variable for e.g. a shared (default) Symfony service appending to an array can potentially result in a leak after a few hundred or thousand requests. If you start with a fresh project and keep that in mind (or limit the amount of loops a worker runs before shutdown + opcache) it is not too big of a problem any more.

One of the biggest things it the community though. Dunglas is not only very nice in person, he's also helpful and the entire FrankenPHP team seems to be very responsive and doesn't judge if you ask "stupid" questions. The Docker containers works out of the box with little intervention needed, so overall DX is great and a very welcome addition to the PHP ecosystem in my opinion.
