Rerolled patch #35 for 11.x branch, please review it.

Thanks & Regards,
Mrinalini

If I search the codebase of 11.x-dev after applying the patch I still see 2 occurences of ->setAccessible(TRUE).

Fix broken test and remaining usage

Applying patch and searching for setAccessible(TRUE) and got 0 results.
Tests are green so seems like a non breaking change.

Adding credits for the aforementioned committer Slack discussions since those are easy to miss. (Didn't do full crediting.)

The last 9.5.x bugfix came out last week (a month later than we might otherwise have done it, just because we skipped the previous month but still had some commits on the branch).

So although we missed April for this one, it's actually ideal timing to do it now. Removing the date from the issue title both because it's passed, and I think this is fine to commit now we're down to security-only on 9.5 now, doesn't need to be a 10.2 beta target or anything.

Committed and pushed 69333763c3 to 11.x (10.2.x) and 9884cfbd90 to 10.1.x. Thanks!

Thank you! 0 additions and 30 deletions

Check the PHP 8.1 Release Notes: Before making any changes, review the official PHP 8.1 release notes and documentation to understand the reasons behind the deprecation or removal of setAccessible() and any recommended alternatives.

Find Affected Code: Identify all occurrences of setAccessible() in your codebase. This can be done through simple text searches or using static analysis tools, depending on the size of your project.

Remove Direct Usage: If the functionality provided by setAccessible() is no longer supported or safe to use, you will need to find alternative approaches to achieve the same functionality without using it. Consider alternatives provided by the language or specific libraries.

Use Reflection Correctly: If you were using setAccessible() to access private or protected properties or methods in tests, consider using the Reflection API to access those elements instead. With Reflection, you can change the accessibility of properties and methods for testing purposes without relying on setAccessible(). This approach allows for better control and reduces potential security risks.

Update Third-Party Libraries: If you are using third-party libraries that rely on setAccessible(), check for updates or look for alternative libraries that are compatible with PHP 8.1 and beyond.

Test Thoroughly: After making the necessary changes, thoroughly test your code to ensure that the removal of setAccessible() does not introduce any regressions or issues in your application.

Update Minimum PHP Version: Update your project's minimum required PHP version to PHP 8.1 to prevent accidental usage of deprecated or removed functions in lower versions.
