Description

This adds support for PHP 8. It looks like Travis doesn't seem to support PHP 8 yet though (I haven't used Travis for ages)?

Closes #3

Yes you still have to use nightly.

Thanks, I've now updated it to use Nightly.

@owenvoke
Thanks for your contribution! 👍
Please look at the related task list for support PHP 8: #3

[owenvoke]

I'm following that task list. 👍🏻 Currently on the last one, but it looks like the only issue in the tests is the servicemanager which needs to be updated to a minimum of 3.2.1 as far as I can tell. Is that ok to do? Or do we still need to support 2.x, which doesn't seem to have the changes.

I'm following that task list.

You have missed an important task:

Modify composer.json to drop support for PHP less than 7.3

Which also means: remove the old version from the Travis configuration. 😉

[owenvoke]

Ah, makes sense. 🤦🏻 I've removed the old versions, and updated to a minum of Service Manager v3.4, which added PHP8 support (and dropped <7.3). And also now removed the old versions from Travis. 😬 Apologies for forgetting this.

Thanks @owenvoke
