Prerequisites
- A system with Ubuntu 24.04
sudo
privileges- Internet Connection
Step 1: Update Your System
Before starting the installation, it’s advisable to update your package list to ensure you receive the latest versions of software and dependencies.
sudo apt update
sudo apt upgrade -y
Step 2: Install Software Properties Common
Ubuntu 24.04 usually includes the software-properties-common
package, but if it’s not installed, you can add it with the following command. This package offers the scripts needed for adding repositories to your system.
sudo apt install software-properties-common -y
Step 3: Add PHP Repository
To access the latest PHP versions, including 8.3, 8.2, and 7.4, it is recommended to add a third-party repository such as the Ondřej Surý PPA, which is well-regarded in the Ubuntu community. This repository offers updated PHP Debian packages for active LTS releases.
To add the PHP repository to your system, use the following commands:
sudo add-apt-repository ppa:ondrej/php -y
sudo apt update
Step 4: Install PHP
Once the repository has been added to your system, you can continue with the installation of PHP and the required modules.
sudo apt install php8.2 -y
Step 5: Verify Installation
After completing the installation, you can confirm that PHP is properly installed by checking its version.
php -v
This command will display the PHP version you installed, along with some additional details. If you have multiple PHP versions installed, it will show the default PHP version. To view other PHP versions, use commands such as php8.3 -v
, php8.2 -v
, and so on.
Step 6: Install PHP Extensions
PHP extensions add or improve functionalities in your PHP installation. For your projects, you might require specific extensions. To install an extension, use the following command, substituting extension_name
with the extension's name and phpX.X
with your PHP version (e.g., php8.2
).
sudo apt install phpX.X-extension_name
For example, to install the MySQL extension for PHP 8.2, use the following command:
sudo apt install php8.2-mysql
Step 7: Install PHP Composer (Optional)
Composer is a tool for managing dependencies in PHP applications. While not mandatory for every project, it is highly useful for developers who want to optimize their workflow and ensure that project dependencies are properly installed and managed. If necessary, you can install Composer by executing the following commands.
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php composer-setup.php
php -r "unlink('composer-setup.php');"

Step 8: Configure PHP (Optional)
Optimizing PHP settings can improve your project's performance. The primary configuration file, php.ini
, is located in specific directories depending on your setup. You can identify the correct PHP version as follows:
- Apache:
/etc/php/X.X/apache/php.ini
- CLI:
/etc/php/X.X/cli/php.ini
- FPM:
/etc/php/X.X/fpm/php.ini
Be sure to replace ‘X.X’ with your PHP version. FPM is typically used with Nginx and occasionally with Apache for applications using non-default PHP versions.
