Early last December, php8.2.0 was released. I did not install it at the first available. I like to wait for the first wave of bugs to be fixed.
Now it is time to upgrade my Web Server’s php engine. Before upgrading, it is PHP8.1.18. The server is powered by Ubuntu 22.04LTS. 1GB Ram, 1Core Intel Processor. on Vultr.com.
I am using Ondrej sury PPA as the source of existing PHP8.1. Since I am already adding this PPA to my system. I just entered the following command to install PHP8.2.
sudo apt install php8.2 php8.2-fpm php8.2-cli php8.2-common php8.2-mbstring php8.2-gd php8.2-intl php8.2-xml php8.2-mysql php8.2-zip php8.2-curl php8.2-bcmath

There are some improvements.
For now, I keep both PHP8.1.18 and PHP8.2.6 on the server. Change the website’s nginx config files, one by one. Test every site to make sure they are good on PHP8.2.
I will take down php8.1 support when I am comfortable with all the websites on my server.
Reference:
