How to downgrade php to php7.4? [Solved]

Hi, I upgraded php to php8,  only to discover many of the web services I run is incompatible.  Well, it almost didn't matter because I run several other versions of php with php-fpm/fastcgi.  Unfortunately for reasons that I have been unable to identify, I can't run correctly nextcloud with php-fpm.
(If I try php73 or php74, it gives internal server error, and if I try php72, I get a severe performance issue).  So I would like to downgrade php to php7.

I have still package files in the cache, but if I uninstall the current version php/php-apache and install older version, pacman complains about /usr/lib/libphp.so not being a symbolic link, and apache wouldn't start and throws an error message

 [mpm_prefork:notice] [pid 71047] AH00170: caug
ht SIGWINCH, shutting down gracefully

in the log.  How can I downgrade php?

There is php7-apache, the module is called mod_php7 and/or php7_module I think.

Thank you very much, the thread looks like what I have been looking for.  I will try and come back later.  As to the news, I had read it before upgrading php @(

OK, I got this, it suffices to install php7, php7-apache etc. and edit apache configuration file with

 LoadModule php7_module modules/libphp7.so

to "downgrade" php.  This settled SIGWINCH apache shutdown issue.  Copying old php.ini with modifications in paths and directory seetings section settled the internal server error issue of Nextcloud.  Thank you very much.
