PHP 8.0/8.1 Support

Hello. I see the latest release from a couple days ago (3.1.12) has a release note of "Updated a lot of code for PHP 8.0 and 8.1 compatibility". Just wanted to check in on the status of that. Is that partially done, mostly done? Am I able to switch my CI3 to 8.1 without getting a bunch of notices and errors? Any thoughts on a timeline?
Thanks a lot. Looking forward to your feedback.

Thank3.1.12

@TheAdmiral ,

CI 3.1.13 has been released... https://codeigniter.com/download

Thanks. Same question then for 3.1.13 or whatever the latest version ends up being. What degree of the PHP 8.1 notices/warnings/errors/deprecations are fixed? Enough for production use?

Do you all think that v3.1.12 was released without full support for PHP 8.1?

Changelog sounds like it has partial support. Would be great if a developer could comment on how much support. Some major bugs fixed? Most major bugs fixed? Enough for production use?

I recommend you check by yourself, and if you would find bugs, report them.
Probably no developers see this thread.

My understanding from Narf is that this provides PHP 8 support. I'm assuming that's full support, and I know I've seen a number of reports and PRs merged over the last few months related to PHP 8, but I wasn't following it that closely.

I would give your app a try locally on PHP 8, run the test suite, do some manual testing, and let us know.

CI 3.1.13 is working with PHP 8.0.3 like a charm. With PHP 8.1.4 I get this error:

Message: ltrim(): Passing null to parameter #1 ($string) of type string is deprecated
Filename: core/URI.php
Line Number: 641

ORIGINAL:

PHP Code:

return ltrim(load_class('Router', 'core')->directory, '/').implode('/', $this->rsegments); 


CHANGED/WORKING:

PHP Code:

return ltrim((string)load_class('Router', 'core')->directory, '/').implode('/', $this->rsegments); 


So create an issue on GitHub for it so that it can be fixed.

What did you Try? What did you Get? What did you Expect?
