scalar_objects VS framework-x

I know there are such experiments, but it's unlikely to become a part of the language any time soon :(

Scalar objects has a prototype implementation since at least 2015: https://github.com/nikic/scalar_objects/issues/20

For the love of god yes please yes this 1000x. I'd like to throw in scalar objects too.

Nikita Popov tried to solve the problem with this extension, but it never got wide support. The problem is that without users asking for this feature, Jetbrains and psalm/phpstan will not integrate it. But w/o their support, users cannot not even try the extension as everything will be shown as error.

These as it would remove the need to even care about the old function names which would exist for B/C purposes. We'd then be able to use primitive types as objects with functions to do all their manipulation as needed.

It's been possible for quite a while but you have to enable a custom extension: https://github.com/nikic/scalar_objects and create an implementation of the class wrapper. I made one quite some time ago which is probably very incomplete: https://github.com/RikudouSage/scalar-objects.

Have a look at Framework X (https://framework-x.org). It's barebones, but provides routing and basic request/response handling to build your own stuff upon. It's based on ReactPHP so you can use it as standalone service or use it in shared hosting with FPM, whichever suits you.

Using FrameworkX default hello world example I get 12.4K req/s on my M1. FrameworkX is using ReactPHP. Unless I'm reading activity monitor wrong it's ~10MB idle and 12,5 MB max.

There are many micro-frameworks available like Slim, Mezzio(with Swoole may be), or if you are into async then you can also try Framework X(from core maintainer of ReactPHP). This frameworks have small footprints compare to Laravel, Symfony, etc. Yes, you can't get things like authentication, routing and other out of the box but they can easily be installed and configured to be used.

I saw it was mentioned in the Framework X

As others have mentioned, in certain scenarios using a long-running application server (rather than mod_php/php-fpm) to serve requests can make sense. There are a number of extensions and libraries available that facilitate this with asynchronous code execution - Swoole has already been mentioned but you may also want to check out ReactPHP (not related to JS React, other than they stole the name) and Framework X

The Framework X is an attempt to make ReactPHP into a micro framework, but I see little mention of it.

Framework-x https://github.com/clue/framework-x

With ReactPHP, I've written a couple websocket apps. Worked pretty great for that. https://framework-x.org/ is also a pretty good place to get started for a simple HTTP microservice-type app.

Yeah ReactPHP will do this. I have an event source server running and it was pretty easy (once you get the hang of using react). I had an nginx proxy in front of it for tls. Have a look at https://framework-x.org too
