How to Install PHP 8.2 on Ubuntu 22.04|20.04|18.04

Today we will learn how to install PHP 8.2 on Ubuntu 22.04|20.04|18.04. PHP is an abbreviation of Hypertext Pre-processor. It is an open-source general scripting language used as a backend programming language for Web applications. In addition to that, it can be used alongside HTML when creating web applications. What separates PHP from other languages such as JavaScript is that for PHP the codes are executed on the server, and HTML scripts are generated and sent to the client.

PHP 8.2 was released in November 2022. This version has many nifty features such as read-only classes, null, false, and true as stand-alone types, deprecated dynamic properties, performance improvements and much more. It also has several bug fixes and performance enhancements over the previous releases.

The features of PHP 8.2 are:

• Fibres – a new feature that allows for lightweight user-land threads that can be scheduled cooperatively by the developer.
• First-class callables for object methods – allowing object methods to be passed around as callables, similar to closures.
• Improved error messages and debugging information – including better error messages for type errors and warnings for invalid parameter types.
• More consistent and improved handling of named arguments – including disallowing passing the same named argument multiple times and enforcing the order of named arguments.
• Improved syntax for enums – including specifying a custom value for each enum constant.

Today we will learn How to Install PHP 8.2 on Ubuntu 22.04|20.04|18.04.

Step 1: Add the PHP 8.2 Surý repository on Ubuntu 22.04|20.04|18.04

The latest PHP packages can be easily installed on Ubuntu 22.04|20.04|18.04 from the  Ondřej Surý’s PHP repository.

First, update the APT index:

sudo apt update

Install the required packages:

sudo apt install -y lsb-release gnupg2 ca-certificates apt-transport-https software-properties-common

Now add the repository to Ubuntu 22.04|20.04|18.04:

sudo add-apt-repository ppa:ondrej/php

Proceed as shown:

 Co-installable PHP versions: PHP 5.6, PHP 7.x, PHP 8.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.

Once installed, check the PHP version:

$ php -v
PHP 8.2.4 (cli) (built: Mar 16 2023 14:34:24) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.2.4, Copyright (c) Zend Technologies
    with Zend OPcache v8.2.4, Copyright (c), by Zend Technologies

Step 3: Install PHP 8.2 Extensions on Ubuntu 22.04|20.04|18.04

For more functionality, we need to install libraries for PHP. The modules, written in C language can be dynamically loaded into PHP or compiled and shared.

The modules can be installed with an APT command with the below syntax:

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

You need to replace module-name with the exact module to be installed. For example:

sudo apt install php8.2-cli

You can make the command neater when installing several modules at once. For example:

sudo apt install php8.2-{bcmath,fpm,xml,mysql,zip,intl,ldap,gd,cli,bz2,curl,mbstring,pgsql,opcache,soap,cgi}

To check the installed PHP extensions, use the command:

$ php -m
