Enable WDDX extension in PHP 7.4 or 8.0

This extension is DEPRECATED and REMOVED as of PHP 7.4 or 8.x. What is WDDX – WDDX (Web Distributed Data eXchange) is a programming language, platform and transport-neutral data interchange mechanism designed to pass data between different environments and different computers.

#cd ~<some_user_home>
#git clone https://github.com/php/pecl-text-wddx.git
#cd pecl-text-wddx 
#/usr/local/bin/phpize 
#./configure
#make 
#make install

Enable the extension into php installation like this:

#cd /usr/local/etc/php/ 
#cat ext-30-wddx.ini
extension=wddx.so

restart php-fpm if needed after this.
Now it’s possible to use www/owncloud or www/nextcloud with PHP 7.4 or PHP 8.0.
