For dev : https://github.com/gggeek/phpxmlrpc ?

For master : delete whole Zen except RPC (and related) ? Or move to https://github.com/laminas/laminas-xmlrpc ?

Wait for https://github.com/LimeSurvey/LimeSurvey/pull/3962 to touch vendor

If we just removed the xmlrpc then users code based on it would be broken, so i would definitely prefer to replace it with a new xmlrpc.
I am not sure how much needs to be updated for it to work, but the previous one seemed lightweight in the usage.

Yes i know

Issue with https://github.com/zendframework/zend-xmlrpc : This repository has been archived by the owner on Apr 28, 2020. It is now read-only.
Issue with https://github.com/laminas/laminas-xmlrpc : no php7.4 support : "php": "~8.1.0 || ~8.2.0 || ~8.3.0",

Then : try https://github.com/gggeek/phpxmlrpc/blob/master/composer.json in vendor "php": "^5.4.0 || ^7.0 || ^8.0", (reason why i wait for vendor update currently)

https://bugs.limesurvey.org/view.php?id=19685 was merged into master, any progress on this ticket?

Can you find another dev for this ?
I really think i don't find a good way (or wait a lot lot lot of time …)

Thank you

I encountered compatibility issues with Zend Framework 1 (ZF1) when using newer PHP versions.
After some investigation, I found the following solutions:

Original Source (zendframework/zf1):
The original ZF1 project reached its end-of-life in 2016. The repository contains a conversion of the ZF1 subversion repo to Git, starting from version 15234 onward. However, Lime (another context) seems to use only a subset of the library/Zend files from this repository.

ZF1 Future (Shardj’s Fork):
I discovered a fork called “ZF1 Future” on GitHub, maintained by Shardj. This fork aims to create a PHP 8.1-compatible version of ZF1.
While it almost worked for me, I still had to apply a manual fix.
If you’re interested, consider contributing by submitting a pull request (PR) to the “ZF1 Future” repository. The last update was about two weeks ago.

Testing and Compatibility:
I tested the solution with the RemoteControl controller. Interestingly, it failed in the same place as it did with PHP 7.4.
So no new issues introduced here.

If you’re interested, consider contributing by submitting a pull request (PR) to the “ZF1 Future” repository. The last update was about two weeks ago.

It can be great !

Then we can move to vendor (it's my solution with gggeek/phpxmlrpc : but a lot of work for adaptation)

Else : add a test is easy : https://github.com/LimeSurvey/LimeSurvey/pull/3975
(i can PR your Pull Request)

1. Add a test : it's needed
2. Way to move to vendor ? Maybe after a PR to ZF1 Future ?

We will workaround the xmlrpc issue for now. Still, in the future, I suggest to keep only json. Obviously, not many people is using XML. If not someerror would have been triggered in the past by users.
