As a developer, keeping my PHP version up to date is essential for performance and security. In this guide, I’ll show you how to install PHP 8.4 on Ubuntu 24.04, configure it for Apache or Nginx, and install necessary extensions.

Whether I’m setting up a new server or upgrading from an older version, these steps will help me get PHP 8.4 running smoothly.

How to Install PHP 8.4 on Ubuntu 24.04

To install PHP 8.4 on Ubuntu 24.04, follow these steps:

Ensure all existing packages are up to date:

sudo apt update && sudo apt upgrade -y

Ubuntu's default repositories may not include the latest PHP version. Add the Ondřej Surý PPA, a trusted source for PHP packages:

sudo add-apt-repository ppa:ondrej/php -y

After adding the repository, update the package list:

sudo apt update

Now, install PHP 8.4:

sudo apt install php8.4 -y

To verify the installation:

php -v

Depending on your project's requirements, you may need additional PHP extensions. For example:

sudo apt install php8.4-mysql php8.4-xml php8.4-mbstring -y

For Apache users:

Install the PHP module for Apache:

sudo apt install libapache2-mod-php8.4 -y

Enable the module and restart Apache:

sudo a2enmod php8.4
sudo systemctl restart apache2

For Nginx users:

Install PHP-FPM:

sudo apt install php8.4-fpm -y

Ensure PHP-FPM is running:

sudo systemctl status php8.4-fpm

Configure Nginx to use PHP by editing your server block configuration to include:

location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/var/run/php/php8.4-fpm.sock;
}

After updating the configuration, restart Nginx:

sudo systemctl restart nginx

By following these steps, PHP 8.4 should be successfully installed and configured on your Ubuntu 24.04 system.
