PHP 8.0 - Did anyone try it on Flarum yet?

Fantomen

Hello,
Today PHP 8.0 was released. Did anyone try the RC, or todays stable, on Flarum yet?

Just tried it out for a short period of time. No issues on my Beta 14 board, but didn't notice any performance increases either.

Edit: I am using PHP 8 RC3

V1Ct0R

Just tried it. After clearing cache PHP Fatal error: Declaration of s9e\SweetDOM\Element::remove(): s9e\SweetDOM\Element must be compatible with DOMElement::remove(): void

V1Ct0R I can confirm this issue after clearing the cache. Want to report it on the bug tracker?

We are currently bounded by several packages that haven't been updated yet. Upgrading for PHP 8 is on the roadmap, but it's not currently supported.

I am not on top of all the changes that php 8.0 brings. But I think there are quite a few backward incompatible changes. This fact can potentially cause dependencies that Flarum has to publish new versions with compatibility only with 8 or higher. Taking that into account, us adopting PHP 8 might push our lower PHP compatibility up as well. And that would have dramatic consequences for our users in terms of their hosting plans.

The first step for us would be to adapt our CI to start testing with PHP 8 on flarum/core and move from there.
