Welcome to the php tutorial!  There are a few things I hope you know before we get started.

• A basic HTML knowledge, so you can format your outputs how you would like.
• PHP installed on your computer, preferably with a web server as well to view the html we create.

All you need to run PHP, and all we will use right now, is notepad and php.  You can get php from php.net.  Simply chose the OS you run, download it, and install it.  Since the majority of the internet uses a PC, we will assume for the sake of the tutorial that you are downloading it for windows.  Mac users have it easy because it comes preinstalled on their system.

To access PHP after it has been installed.  Open cmd.exe and navigate to the folder of choice (“cd c:\php\” if you saved it in c:\php\).  Macs just open terminal and you are set to go.

Lets test it now.  Open a new text document and type:

<?php
echo "Hello World!";
?>

Save it as “hello.php”. With cmd.exe or terminal still open, just type:

php hello.php

You should see the output “Hello World!”, and you have just written your first PHP script.
