==================
We are running LS 3.22.17 and are unable to upgrade to LS 5. Is 3.22.17 compatible with PHP 8? Our current version of PHP is 7.4.

Thank you for any info. I saw another thread that said LS 5 and up was compatible w/ PHP 8, but not version 3.x.
 

I recommend to stay on PHP 7.X with LS3. LS3 will run with PHP 8.0.X, but issues may occur and there is no testing of LS3 under PHP 8. You won't find an official recommendation to run LS 3 under PHP 8. Reported bugs may be fixed if reported, but investing that time in LS5 seems to be a better investment.

You can install LS3 on PHP8 but it is officially not supported.
LS5 supports currrently 8.0, but not 8.1, yet.

Hi, as PHP 7.4 is reaching its end of life November, 28th, I would like to ask whether the LTS 3.x will or does already officially support PHP 8.

In the release notes I find this:

> Changes from 3.26.3 (build 210511) to 3.26.4 (build 210517) May 17, 2021
[...]
> -Fixed issue #17236: PHP 8 not supported (Carsten Schmitz)

Does this mean that from 3.26.4 up, PHP 8 is supported?

Looking closer into the topic, as the date for end of support for 7.x approaches, I find that unfortunately there is no reliable info at bugs.limesurvey.org/view.php?id=17236 ; the relevant links mentioned there do not work, and so we cannot be sure whether this has been resolved, and PHP 8 can now be used with the LTS or not.

Can anybody update us on this topic?

I would rather make a comment in the bug reports than here. The developers don't follow the forum very closely and people here in the forum are mainly users helping users. So I think chances are higher that you get feedback in the bug tracker.

Thanks and yes, that was my first idea - but the bug is locked and cannot be commented any more unfortunately.

The best idea might be to file a new bug, should I do that?

Oh, ok. Seems like I can add notes still, but yes, the bug report is marked as closed.

Now, seeing that this all is about LS 4.x (which then turned LS 5.x) and reading through the notes, I get the impression that there were/are no plans on making LS 3.x compatible with PHP 8, as the fix provided was only for LS 4.

So my guess is, that support for LS 3.x will run out soon.

Not sure what the best way is to ask this question. Are you a paying customer (e.g. ComfortUpdate)? Then you might be able to open a suppor ticket directly with the Limesurvey GmbH. However, the support might just be for anything related to the paid service and they still might not answer your inquiry.

Not sure if opening a bug ticket referring to LS 3 will give you an answer, but it might be worth a try.

Thanks a lot! I just filed  bug #18484 .

There are many offers to prolong the usage of PHP 7.4.
LS3 seems to have too many old dependencies.
I think LS3 will be supported in 2023, but only PHP 7.4.
For the SaaS business they can use PHP 7.4. for the next years.
To invest a lot of developer time into making LS3 running under PHP 8.1.seems to be wasted time.
But that is my guess,

PHP 8 reaches EOL at 26th Nov 2023.
And to support PHP 8.1. there is still a lot of work for LS5.
 

Got feedback from the LimeSurvey CTO.

The stance is that PHP8 is already supported for LS3, general LTS support will be continuing until mid 2023

Good news.
PHP 8.0 should be save for LS3 and LTS is extended for another six months.

 

Hi and thanks for checking! This is very good news!
