There is a lot of redundant code. Could you move this into a method?

[arshidkv12]

ok.

If we drop support for anything less than PHP 8.1, we could just delete the calls to setAccessible(). Unfortunately, 8.1 was only release 4 years ago, which might be a little too recent. What do you think @odan ?

[odan]

@akrabat I think keeping PHP 8.1 adds extra maintenance overhead (CI jobs, tests, etc.).

I would suggest aligning with PHP’s official security timeline and keeping 8.1 support only until 31 Dec 2025 (supported versions).
That’s just one month away, so we could already prepare to drop it in the next release.

Thanks for the PR. We are working on the changes for PHP 8.5 in this PR: #3415
