Allow Symfony 8; converted config to PHP

[knallcharge]

may need a new major version as PHP was bumped to ^8.4

[alexandre-castelain]

Thanks for this PR ! :)

[knallcharge]

I reverted the bump to PHP 8.4 as composer.json still allows older Symfony-versions. You may consider issuing a new major that drops old Symfony- and PHP-versions, but I kept the same code running with Symfony 6-8 and PHP 8.1-8.5 without any problems so you may as well stick with the current composer.json :)

[alexandre-castelain]

Yeah, but I want to use the PHP configuration file, because the xml loader is deprecated ! :)

[knallcharge]

Dind't check, but wouldn't the PHP-loader also work with the older Symfony/PHP-versions? Anyhow whatever number the new version may have, I'll use it ;)

@knallcharge Sorry for the delay, I only just saw your PR.

Indeed, we have to stay compatible with older Symfony versions.

Some checks have failed. There are a couple of things to address before we can merge:

• Code Analysis: Please remove the ignoreErrors line from the phpstan.neon.dist file.
• Code Style: The code needs to be linted using PHP-CS-Fixer. You can find the instructions here.

Once these changes are made, I'll release a new minor version ;)

@cmen Errors should be fixed :)
(can I trigger a new build myself to verify the changes?)

I added a missing return type. All is good now. Let's go for the merge 🚀
