This guide walks through the steps to install PHP 8.4 on Ubuntu 24.04 with minimal friction. Step 1: Update the System Before installing any new packages, ensure your system is up to date. Run the following commands to refresh the package list and apply available updates: sql sudo apt update sudo apt upgrade -y This keeps the system stable and reduces the chances of encountering version-related conflicts during PHP installation.

2. https://docs.vultr.com/ Step 2: Add PHP Repository Ubuntu’s default package sources may not include the latest PHP version, especially PHP 8.4. To access it, add the ondrej/php repository, which maintains updated PHP packages for Ubuntu systems. sql sudo apt install software-properties-common -y sudo add-apt-repository ppa:ondrej/php sudo apt update Adding this repository ensures PHP 8.4 is available to install directly through apt. Step 3: Install PHP 8.4 Once the repository is added and the package list refreshed, proceed to install PHP 8.4: nginx sudo apt install php8.4 -y After the installation completes, verify the version: nginx php -v You should see output confirming that PHP 8.4 is installed and active. Step 4: Install Common PHP Extensions Depending on the application or framework you plan to run, additional PHP modules might be required. Some common ones include: python sudo apt install php8.4-cli php8.4-common php8.4-mysql php8.4-xml php8.4-curl php8.4- mbstring php8.4-zip php8.4-bcmath php8.4-gd -y

Step 5: Configure PHP 8.4 Settings (Optional) You may want to adjust some settings in the php.ini file, such as memory limits, file upload size, or error reporting level. The location of the php.ini file depends on whether you're using PHP with Apache or Nginx: ●For Apache: /etc/php/8.4/apache2/php.ini ●For Nginx (with PHP-FPM): /etc/php/8.4/fpm/php.ini Use a text editor like nano to modify: bash sudo nano /etc/php/8.4/fpm/php.ini After editing, remember to restart the web server or PHP-FPM to apply the changes. Step 6: Configure Web Server (Apache or Nginx) If you're using Apache: lua sudo apt install libapache2-mod-php8.4 -y sudo systemctl restart apache2 If you're using Nginx with PHP-FPM: nginx sudo apt install php8.4-fpm -y sudo systemctl restart php8.4-fpm Make sure your web server configuration points to the correct PHP socket or port if using PHP-FPM.

4. https://docs.vultr.com/ Step 7: Test PHP Installation Create a simple PHP file to confirm that PHP is working properly through the web server. Use this command to create the file: css sudo nano /var/www/html/info.php Insert the following line: php <?php phpinfo(); ?> Save and close the file, then open a web browser and navigate to: pgsql http://your-server-ip/info.php You should see a PHP information page detailing the current version, loaded modules, and configuration options. Step 8: Clean Up (Optional) Once you've confirmed PHP is working, it’s a good idea to remove the info.php file to prevent exposing sensitive configuration details. bash sudo rm /var/www/html/info.php
