I recently purchased a headless server and I'm planning to set it up as a web server. However, I'm not certain if I can install PHP on it since it doesn't have a graphical interface. I want to use PHP to develop dynamic websites and run scripts on the server. Can anyone tell me if it's possible to install PHP on a headless server without a graphical interface? If so, could you please guide me through the installation process? Thanks in advance for your help!

Absolutely! I've successfully installed PHP on a headless server without a graphical interface, and it's been an excellent experience for running web applications and scripts.
To install PHP, you'll need to utilize the command line interface (CLI) to execute the installation process. Here's a step-by-step guide based on my personal experience:
1. Establish a SSH connection or any other remote access method to your headless server.
2. Begin by updating the package manager on your server using the command: `sudo apt update`
3. Once the update is finished, you can proceed with the PHP installation by executing: `sudo apt install php`
4. Additionally, you may want to install additional PHP extensions or libraries based on your requirements. Simply append their names to the installation command. For instance, to install the GD extension, you can use: `sudo apt install php-gd`
After the installation, you can verify the installed PHP version by running: `php -v`. This command will display detailed information about the installed PHP version on your server.
To further tweak PHP's configuration, you might need to modify the php.ini file situated in the /etc/php/ directory. This file allows you to customize various PHP settings, including memory limits, error reporting, and more.
Keep in mind that without a graphical interface, you'll need to utilize command-line text editors such as nano or vim to access and modify files. Although it might seem daunting at first, it quickly becomes familiar and efficient.
Installing PHP on a headless server opens up limitless possibilities for web development. If you have any further questions or need assistance, feel free to ask. I'm here to help!
