Fixed PHP 8.1 Compatibility

[Kirby]

Affected version

2.2.7 PL 1

Probably already known:

It seems like XenForo ist currently not compatible with PHP 8.1 due to missing return type declarations on many methods, most notably on classes implementing core interfaes like \ArrayAccess

This does generate error messages like

An exception occurred: [ErrorException] [E_DEPRECATED] Return type of XF\Session\Session::offsetExists($key) should either be compatible with ArrayAccess::offsetExists(mixed $offset): bool, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in src/XF/Session/Session.php on line 177

when running in development mode.

While PHP 8.1 is still a a few month away from stable, it would be nice to have this resolved before release date

The changes are fairly extensive and may also apply to third party dependencies which we may need to manually patch so, yeah, we're aware and it's mostly in hand.

We may not be able to guarantee support by the stable release. A future release announcement will mention PHP 8.1 when compatibility is added.

 

[Chris D]

XF 2.2.8 adds initial support for PHP 8.1.

I strongly suspect there will be some underlying things we have missed, but I'm currently running it in development with no obvious issues thus far.

We wouldn't recommend switching to PHP 8.1 in production but we do call on as many people as humanly possible to test this in staging/testing servers so we can cover off any lingering incompatibilities.

Do you run any add-ons? Just want to see which one is already compatible with 8.1

If you're using Centmin Mod, you can also try PHP 8.1.0 with new libgd 2.3.3 version to see how Xenforo image features work with a newer GD PHP library https://community.centminmod.com/th...-php-extension-support-in-123-09beta01.22211/

PHP 8.1.0 with new libgd 2.3.3 version

Nice addition
Thanks Eva.

@eva2000 Which one do you prefer? GD vs Imagick?

 

[eva2000]

I usually use Imagick myself but newer GD 2.3.3 is new so hard to say.

Thanks Eva.

Looks good - let us know how it fairs with Xenforo

After an hour or so on www.theparacast.com, everything seems to function without any errors. Of course, I can switch back to the latest PHP 8.0.x quickly if things go awry. So this isn't a serious risk here. Our WordPress blog also seems to run well.

Bannedavatar runs fine here..
