"Hello, World!" in PHP
How to do "Hello, World!" in PHP.
// hello-world.php <?php echo 'Hello, World!'; ?>
Even though PHP is mostly used for adding server-side functionality to web pages, PHP is actually a self-containing language that can be run on a lot of different platforms, both in a web server and completely stand-alone. When PHP is run inside a web server, the echo function renders output to the response of an HTTP request. When PHP is run from the command line, it prints to the console.
