# Installing and Configuring Apache & Nginx with Multiple PHP Versions #
# Apache will run on port 8080 and will be behind Nginx                #
# Nginx will serve as a reverse proxy for Apache Sites                 #
# Nginx will act as the primary web and caching server                 #

# To Switch PHP FPM Version for Apache the following commands should be used
# sudo a2disconf php<ver>-fpm && sudo a2enconf php<ver>-fpm
sudo systemctl reload apache2

# To enable Nginx Reverse Proxy for Apache, add the following to the Nginx specific site configuration
# location ~ \.php$ {
#         proxy_set_header X-Real-IP $remote_addr;
#         proxy_set_header X-Forwarded-For $remote_addr;

#         proxy_pass http://127.0.0.1:8080;
# }

# To switch CLI PHP version to another than the default use the following syntax
# sudo update-alternatives --set php /usr/bin/php<version>

# For Example (Replace 8.2 with your PHP version)
# sudo update-alternatives --set php /usr/bin/php8.2
# sudo update-alternatives --set phar /usr/bin/phar8.2
# sudo update-alternatives --set phar.phar /usr/bin/phar.phar8.2
# sudo update-alternatives --set php-config /usr/bin/php-config8.2
# sudo update-alternatives --set phpize /usr/bin/phpize8.2
