Linux (Ubuntu/Debian):

Verify PHP Installation:

1. Open a web browser and navigate to http://localhost/ (or the URL of your web server).
2. Create a new file called info.php with the following content: <?php phpinfo(); ?>
3. Upload the file to your web server's document root directory.
4. Access the file in your web browser to verify that PHP is installed and working correctly.

Additional Steps:

1. Configure your web server to use PHP (e.g., Apache, Nginx).
2. Install additional PHP extensions or libraries as needed (e.g., MySQL, GD).
3. Set up a code editor or IDE (e.g., Visual Studio Code, Sublime Text) to write and debug PHP code.

Remember to restart your web server after installing PHP to ensure that the changes take effect.
