Symfony version(s) affected

(4.4), 5.3, 5.4, 6.0, 6.1, 6.2

Description

In November 2022, PHP 8.2 will be released and we should be prepared. In this PR, I'd like to track the efforts necessary to make all actively maintained branches ready for that release.

Ready means: if an application uses features of PHP 8.2, Symfony must not blow up.

We do already have a GitHub action that tests all branches with PHP 8.2. This action will constantly monitor Symfony's compatibility with the current state of PHP 8.2.

I will update this issue as we progress.

How to Contribute

If you want to join the effort, please start with the components and bridges. Fixing those will also fix many broken bundle tests. Reminder: We treat compatibility issues as bugs. As always, please fix bugs on the lowest maintained branch that suffers from the bug.
