Follow the next steps to install PHP 8.2 on your latest Ubuntu Servers

Step 1: System Update

Before diving into the installation process, it’s crucial to ensure that your system is up to date. Open a terminal and execute the following commands:

samm@php:~$ sudo apt-get update -y

Step 2: Add the Ondrej Sury Repository to the PPA

For PHP 8.2 to operate seamlessly on Ubuntu 22.04, it’s imperative to incorporate the Ondrej Sury PPA into the system. Presently, the responsibility of overseeing the PHP repository lies in the hands of Ondrej Sury. However, it’s important to note that since this PPA is not under active review, the act of installation from it doesn’t assure the fulfillment of all prerequisites.

In our terminal, use the following command to add this PPA.

samm@php:~$ sudo add-apt-repository ppa:ondrej/php

Once the installation has been completed, an additional repository update is necessitated to ensure the implementation of the changes.

samm@php:~$ sudo apt-get update -y && sudo apt-get upgrade -y

Step 3: Install PHP 8.2 on Ubuntu Server 22.04

Now, you should be ready to proceed with the installation of PHP 8.2 on your Ubuntu 22.04 Linux machine. To install PHP 8.2, you can use the following command::

samm@php:~$ sudo apt install php8.2 -y

Once the installation is complete, you’ll have PHP 8.2 ready to go on your server. This accomplishment can be attained by executing the subsequent command:

samm@php:~$ php -v
PHP 8.2.5 (cli) (built: Apr 14 2023 04:39:46) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.2.5, Copyright (c) Zend Technologies
    with Zend OPcache v8.2.5, Copyright (c), by Zend Technologies

This command will display the PHP version and relevant information. If you see PHP 8.2 listed, congratulations – you have successfully installed PHP 8.2 on your Ubuntu Server 22.04!.

Step 4: Add Extensions for PHP 8.2

In addition to PHP itself, you will probably want to install supplementary PHP modules. To install additional modules, you can make use of the following command, replacing [module-name] with the package you wish to install.

sudo apt-get install php8.2-<module-name>

Simultaneously install multiple packages is also possible. Consider installing the most frequently required modules with these recommendations.

samm@php:~$ sudo apt-get install php8.2-{common,cli,fpm,mbstring,zip,pgsql,mysql,mongodb,redis,memcache,memcached,opcache,gd,mcrypt,apcu,curl,xml,xmlreader,bcmath,readline,sockets,imagick,bz2,pdo,dom}

Executing this command will result in the installation of the subsequent modules:

• php8.2-cli – command interpreter, useful for testing PHP scripts from a shell or performing general shell scripting tasks
• php8.2-common – documentation, examples, and common modules for PHP
• php8.2-mysql – for working with MySQL databases
• php8.2-zip – for working with compressed files
• php8.2-gd – for working with images
• php8.2-mbstring – used to manage non-ASCII strings
• php8.2-curl – lets you make HTTP requests in PHP
• php8.2-xml – for working with XML data
• php8.2-bcmath – used when working with precision floats

The comprehensive list of loaded PHP modules can be viewed by utilizing the following command:

samm@php:~$ php -m

Step 5: Configure PHP 8.2 Settings (Optional)

While PHP is now installed, you might want to tweak some settings to match your project requirements. The PHP configuration files are located in the /etc/php/8.2/ directory. You can edit the php.ini file using your preferred text editor. For example:

samm@php:~$ /etc/php/8.2/cli/php.ini

Feel free to adjust settings such as memory limits, error reporting levels, and more in order to align them with the specific needs of your application.

Step 6: Using PHP 8.2 with Nginx/ Apache web server

We will explore configurations for both Nginx and Apache web servers to host your PHP application.

PHP 8.2 application with Nginx web server

In the case of Nginx, PHP code is commonly executed through a distinct process known as PHP-FPM (FastCGI Process Manager). PHP-FPM, operating as a daemon, actively awaits incoming PHP requests and processes them in dedicated instances. In this setup, Nginx’s role is to forward incoming requests to PHP-FPM, thus facilitating the actual execution process.

Before proceeding, ensure you have installed the Nginx web server.

$ sudo apt install nginx php8.2-fpm

Access your Nginx server configuration and insert the subsequent block within the existing http block. By incorporating this configuration, PHP requests will be systematically routed and seamlessly executed by PHP-FPM:

$ sudo vi /etc/nginx/nginx.conf
server {
    listen 80;
    server_name example.com;
    root /var/www/myweb;
    index index.php index.html;

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

Validate Nginx configuration is ok.

$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Restart Nginx web server after the configuration.

$ sudo systemctl restart nginx

PHP 8.2 application with Apache web server

Within Apache, we can utilize an integrated module called mod_php to directly handle PHP code within the Apache process itself.

However, before proceeding, ensure you have installed the Apache web server package, as well as PHP and the Apache PHP module.

$ sudo apt install apache2 libapache2-mod-php8.2 

Enable mod_php module:

$ sudo a2enmod php8.2

Restart Apache web server after the configuration.

$ sudo systemctl restart apache2

Step 7: Test PHP with a Web Server

Once your preferred web server is installed, create a test PHP file in the web server’s document root directory. For example:

echo "<?php phpinfo(); ?>" | sudo tee /var/www/html/phpinfo.php

Access this file through your web browser by navigating to http://your_server_ip/phpinfo.php. If the page displays PHP information, PHP 8.2 is working correctly with your chosen web server.

You should see a page displaying detailed information about your PHP installation.
