Updated to php 8.0

[ernst77]

Minimal changes, I've only added er to the Match class and match variables.
Also upadted phpUnit to the version that supports php 8.0, because of this had to drop support for older php versions.
I guess it's okay as older PHP versions are not supported anymore...

Hi Ernest! Thank you for your effort.

I see that old PHP versions are still in use and I think it's better to add support of PHP 8 without dropping support for the old ones.

We cannot run phpUnit tests then, as the phpUnit version that supports PHP 8 dropped support for php below 7.3 :) We could tag this as a major version upgrade as it will have breaking changes for older php versions.

Hmm... I'll try to read about this. Actually, I migrated to Python as a main language and don't follow PHP news 😄

No worries, when you have time...
Well PHP language is moving quite quickly nowadays, I work constantly on it and cannot keep it up 😄

Well, I think all the older versions and hhvm can be dropped. Don't think that there is a big issue, if a new major version just supports >= 7.3. If there is really a fix to be made in the classes, there is always the possibility for a backport of the fix to version 1.

It would be possible to have e.g. PHPUnit 8 and PHPUnit 9, but that would only support >= 7.2 and as 7.2 is already unsupported, I think it can be dropped as well. If anyone want's to support version 1 and 2 in his project, there is always the possibility to have e.g. "^1.0|^2.0" in the composer version constraint.
