  2. Update the package repository and ensure that the server is up to date by running the following command: sudo apt update && sudo apt upgrade
  3. Install required packages for Phalcon's compilation process: sudo apt install -y software-properties-common sudo add-apt-repository ppa:phalcon/stable sudo apt update sudo apt install -y php7.x-phalcon # Replace '7.x' with the version of PHP installed on your server, e.g. "7.4"
  4. Once the installation is complete, restart your web server to load the Phalcon extension: sudo service apache2 restart # Replace 'apache2' with your web server (e.g., nginx)
  5. To verify that Phalcon is successfully installed, you can create a PHP info file. Create a new file called info.php in your web server's document root (e.g., /var/www/html/), and insert the following code:

Note: The specific commands may vary depending on your Linux distribution, web server software, and PHP version. Be sure to adjust the commands as necessary.
