php tutorial
// Firstly you must have PHP installed & running a web server
// This could be Apache, Nginx, etc...
// Or for quick testing purposes and for the purpose
// of this example, you could run
// PHP's own dev server from a shell
php -S 127.0.0.1:8080 -t your-web-directory-location
// This will start a web server on localhost port 8080
// The -t switch sets the document root, this is where your
// home page, typically index.php will be situated
// very basic index.php example
<?php
echo "Hello, world!";
?>
// You can now go to a browser and enter 127.0.0.1:8080
// You will presented with your simple web page
// Hello, world!
