Hello World

Open a PHP block

PHP code lives inside <?php ... ?> tags. A file can mix HTML and PHP later.

<?php
echo "Hello, World!\n";

Run from the CLI

From the folder that contains the file:

php hello.php

View in a browser

With php -S localhost:8000 running, visit http://localhost:8000/hello.php.

Echo and print

• echo sends output to the response or terminal
• Statements usually end with a semicolon
• Omit the closing ?> in pure PHP files to avoid accidental whitespace
• Errors appear based on your display/error settings
