How to Install PHP 7.4 FPM on Ubuntu 18.04
Other than developing web applications, I'm also acting as system administrator. Most of my clients are not very familiar with Linux environment.
Some of the servers I maintained are still running Ubuntu 18.04. Although it's still being actively maintained, the latest official PHP version from Ubuntu is 7.2.24. Some of our Laravel applications are newer, hence it require PHP >= 7.4. There's no other way than upgrade our PHP version.
PHP 7.2.24-0ubuntu0.18.04.10 (cli) (built: Oct 25 2021 17:47:59) ( NTS )

To upgrade our PHP version to 7.4, we must add a PPA repository maintained by Ondřej Surý called
ondrej/php. First, let's update our system's apt repository first.
Update apt Repository
First, we need to make sure that our system is up-to-date. On your terminal, run this command:
$ sudo apt update
$ sudo apt upgrade
Before we add a new repository, we need to install necessary package:
$ sudo apt -y install
ondrej/php repository, run this command:
$ sudo add-apt-repository ppa:ondrej/php
It will respond with message like below:
Co-installable PHP versions: PHP 5.6, PHP 7.x and most requested extensions are included. Only Supported Versions of PHP (http://php.net/supported-versions.php) for Supported Ubuntu Releases (https://wiki.ubuntu.com/Releases) are provided. Don't ask for end-of-life PHP versions or Ubuntu release, they won't be provided.
Debian oldstable and stable packages are provided as well: https://deb.sury.org/#debian-dpa
You can get more information about the packages at https://deb.sury.org
IMPORTANT: The <foo>-backports is now required on older Ubuntu releases.
BUGS&FEATURES: This PPA now has a issue tracker:
1. If you are using php-gearman, you need to add ppa:ondrej/pkg-gearman
2. If you are using apache2, you are advised to add ppa:ondrej/apache2
3. If you are using nginx, you are advised to add ppa:ondrej/nginx-mainline
PLEASE READ: If you like my work and want to give me a little motivation, please consider donating regularly: https://donate.sury.org/
WARNING: add-apt-repository is broken with non-UTF-8 locales, see
https://github.com/oerdnj/deb.sury.org/issues/56 for workaround:
# LC_ALL=C.UTF-8 add-apt-repository ppa:ondrej/php
More info: https://launchpad.net/~ondrej/+archive/ubuntu/php
Press [ENTER] to continue or Ctrl-c to cancel adding it.
Just press ENTER to continue with repository addition.
The last step is to install PHP 7.4 on Ubuntu 18.04 Bionic. Before installation, update system package list on added repositories.
PHP 7.4 Installation
Let's update our system's repository again.
$ sudo apt update
Then we can continue to install PHP 7.4 FPM on Ubuntu 18.04:
$ sudo apt -y install php7.4-fpm php7.4-bcmath php7.4-curl php7.4-gd php7.4-mbstring php7.4-mysql php7.4-xml php7.4-zip
To verify that our installation went correctly, enter this command:
$ php -v
It must respond with something like this:
PHP 7.4.25 (cli) (built: Oct 22 2021 12:33:59) ( NTS )
