Ubuntu 24.04 should come with software-properties-common installed, but in case it isn’t, you can install it using the following command. This package provides necessary scripts for adding repositories to your system.
sudo apt install software-properties-common -y
Step 3: Add PHP Repository
To ensure access to the latest PHP versions, including 8.3, 8.2, and 7.4, it’s recommended to add a third-party repository such as the Ondřej Surý PPA, which is widely trusted in the Ubuntu community. This repository contains updated PHP debian packages for the active LTS releases.
Use the following commands to add PHP repository to your system:
sudo add-apt-repository ppa:ondrej/php -ysudo apt update
Step 4: Install PHP
Once the repository is added to the system, you can proceed with the installation of PHP and required modules. You can choose to install PHP 8.3, 8.2, 8.1, 8.0, 7.4, 7.3, 7.2, 7.1, 7.1, or 5.6 depending on your application requirements.
- For PHP 8.3
sudo apt install php8.3 -y - For PHP 8.2

sudo apt install php7.4 -y
You can also install multiple PHP versions on your system as required.

PHP extensions enhance or add functionalities to the PHP installation. You might need specific extensions for your projects. To install an extension, you can use the following command, replacing extension_name with the name of the extension and phpX.X with your PHP version (e.g., php8.3).
sudo apt install phpX.X-extension_name
Here’s an example of installing the MySQL extension for PHP 8.3:
sudo apt install php8.3-mysql
Step 7: Install PHP Composer (Optional)
Composer is an dependency management tool for the PHP applications. While Composer is not essential for every project, it’s a valuable asset for any developer looking to streamline their workflow and ensure project dependencies are properly installed and managed. If required, you can also install it by executing the following commands.
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"php composer-setup.phpphp -r "unlink('composer-setup.php');"
Step 7: Configure PHP (Optional)
Optimizing PHP settings can enhance your project’s performance. The main configuration file, php.ini, resides in specific locations based on your setup. You can find the correct php version as below:
- Apache:/etc/php/X.X/apache/php.ini
- CLI:/etc/php/X.X/cli/php.ini
- FPM:/etc/php/X.X/fpm/php.ini
