}

Step 2: Reload Nginx

Reload the Nginx service to apply the changes made in the Nginx configuration:

sudo systemctl reload nginx

Step 3: Test PHP

To test the PHP, you need to create a file containing PHP information and save it as ‘index.php’ in a specific location:

echo "<?php phpinfo(); ?>" | sudo tee /var/www/html/index.php
