Step 1 : Update the System : Make sure your package list and installed packages are up to date.

sudo apt update

Step 2 : Install Software Properties Common

Step 3 : Add the Ondřej Surý PPA

You need to add the Ondřej Surý PPA to your system:

Step 6 : Configure Nginx to use PHP

Create a new Nginx server block configuration:

sudo nano /etc/nginx/sites-available/example.com

Replace "example.com" with your domain or server IP. Add the following configuration:

server {
    listen 80;
    server_name example.com www.example.com;

    root /var/www/html;
    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ =404;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php8.2-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

    location ~ /\.ht {
        deny all;
    }
}

Save and exit the file. Create a symbolic link to enable the site:

sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/

Test the Nginx configuration:

sudo nginx -t

If the test is successful, reload Nginx to apply the changes:

sudo systemctl reload nginx

Step 7 : Verify PHP Installation

Create a PHP file in your web root to verify the installation. For example:

sudo nano /var/www/html/info.php

Add the following content:

<?php
phpinfo();
?>

Save the file and access it in your web browser (e.g., http://your_domain_or_ip/info.php). You should see the PHP information page.

You should now have PHP 8.2 installed and configured with Nginx on Ubuntu 22.04.
