Introduction to PHP for Website Developers

What is PHP? I could just have you visit php.net and find out for yourself, but although you would find out a lot of information about PHP you probably wouldn't really understand its use/purpose.

When you create a website using just HTML and CSS, it's "static". This means that no matter who accesses each page, all of the pages will look the same.

The reason for this is that with static web pages, the server simply regurgitates the same page (code) to each viewer. In most cases, you are going to want something better: a dynamic web page.

Adding a subdomain to your website

Subdomains allow you to denotate to your website visitors that they are viewing a particular section of your website. An example of a subdomain would be mail.google.com. "mail" is a subdomain of "google.com", with a period in between. Generally, subdomains will have a folder on the same server as the main website for all of the subdomain's files.

This tutorial will show how to add a subdomain to your website if it uses CPanel or something similar. CPanel is a very common and popular control panel for websites, and this tutorial will be using screenshots I've taken (myself) from the (interactive) demo on CPanel's website:
