[horde] php8 fatal errors

[Ferdinand Gruber]

Hi,

since upgrade from PHP7 to PHP8 horde creates a lot of fatal errors:

*Fatal error*: Uncaught ArgumentCountError: Too few arguments to 
function Horde_ErrorHandler::errorHandler(), 4 passed in 
/usr/share/php/PEAR/Horde/Injector/DependencyFinder.php on line 61 and 
exactly 5 expected in /usr/share/php/PEAR/Horde/ErrorHandler.php:153

My system is openSUSE version 15.4.

After upgrade from SUSE 15.3 to 15.4 PEAR was not installed.

So I installed the package php8-pear manually.
The include_path in php.ini is set to:

include_path= ".:/usr/share/php8:/usr/share/php/PEAR"

The PEAR folder exists and seems up to date.
Thank you in advance for every hint.
