Summary18247: php version 8 and remote control, error in bigdata.php
Description

Hi running limeSurvey on a shared host. Linux based LiteSpeed server, MySQL Version 10.5

LimeSurvey version 5.3.23 release 220705. Fresh installation on both filesystem and database.

Using the remote control API. Everything is working without problems on PHP 7.4. However when I change to PHP version 8 or PHP version 8.1, the remotecontrol calls fail.

If I change the PHP version to 7.4 and repeat. It works again. I have other applications (such as Drupal) working in the same environment on the same server. For this problem there were no other applications installed.

Steps To Reproduce

Steps to reproduce

Set PHP Version to 8 or later.

Complete fresh installation of LimeSurvey. No need to create any surveys.

Activate the JSON-RPC api, copy the URL

Access the site using remote control. First call get_session_key will fail.

Expected result

The site returns the session key

Actual result

The call fails and returns a null result.

I turned on debug level 2 and caught the response from the server and it is pointing to the error:

"BigData::hasStream(): Argument #1 ($result) must be passed by reference, value given" on line 24 of application/libraries/BigData.php(24)

Complete returned information attached in error.html.

The function array_reduce did change in PHP version 8.

TagsNo tags attached.

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

Which minor vesion of PHP are you using?

Thanks @gabrieljenik! I am comfortable with PHP and server apps but don't know my way around GIT.

I manually added the change to my test environment (5.3.24) and tested on PHP 7.4, 8.0 and 8.1. All worked.
