Installing PHP is an essential part of any web development pipeline. Without a server-side scripting language, you cannot implement logic in your pages.

In this article, we will see how to install PHP in Ubuntu 20.04 and 18.04 LTS versions. The process itself is quite simple and almost identical for both versions.

We’re going to look at two methods of installing PHP on your Ubuntu machine, one with Apache and one with Nginx.

Installing PHP with Apache

If you are using Apache as your primary web server, use the following command to install PHP with the Apache PHP module.

On Ubuntu 20.04 the following command installs PHP 7.4, and on Ubuntu 18.04 it installs PHP 7.2.

sudo apt update
sudo apt install php libapache2-mod-php

Restart Apache after installing the packages to load the PHP module.

sudo systemctl restart apache2

Installing PHP with Nginx

Nginx does not have built-in support for processing PHP files, which means that PHP-FPM, also known as fastCGI Process Manager, must be used to process PHP files.

sudo apt update
sudo apt install php-fpm

Once the installation is complete, the FPM service is automatically started. To check the status of the service, use this command.

php7.4-fpm system status

Once you are sure the service is installed and running, make the following addition to your Nginx server block so it can process the PHP files.

Server {

# … another code

location ~ .php$ {
allows snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php7.4-fpm.sock;
}
}

Then restart the Nginx service for the changes to take effect.

sudo systemctl restart nginx

How do I install PHP on Ubuntu 18.04 LTS?

If you are using Ubuntu 18.04, the commands to install PHP via Apache or Nginx remain the same. However, note that both commands install PHP 7.2, as this is the default version of PHP in the repository.

To verify that the FPM service works on Ubuntu 18.04 LTS, you need to modify the above command to make sure you are getting the correct version of PHP.

php7.2-fpm system status

The basic functionality of PHP can let you down. There are many PHP extensions/libraries you can use to speed up your work.

To install it, use the apt command with the following syntax.

sudo apt install php-packagename

For example, MySQL and GD, some of the most widely used PHP extensions, can be installed this way.

sudo apt install php-mysql php-gd

Depending on the server you are using, you may need to restart Apache or the PHP FPM service after the installation is complete.

Testing your installation is fairly simple. Create a new info.php file in the /var/www/html directory and insert the following code.

One of the Debian developers, Ondrej Suroj, manages the PHP version repository. Here’s how to activate the deposit.

sudo apt install software-properties-common
sudo add-apt-repository ppa:ondrej/php

You can now install almost any version of PHP using the apt command.

sudo apt install php(version)

A z. B. To install PHP 7.2, the command should look like this

sudo apt install php7.2

The same applies to the installation of packages.
